48352.

TRUE OR FALSE : The nucleus and the electrons are the two parts of the atom that are attracted to each other because of electrostatic force.

Answer»

Oppositely charged particles attract each other, while like particles repel one another. Electrons are KEPT in the orbit around the nucleus by the ELECTROMAGNETIC FORCE, because the nucleus in the center of the ATOM is positively charged and ATTRACTS the negatively charged electrons.hope it helps you !!mark me as the brainliest!!

How many bonding pairs of electrons are between two atoms of chlorine?

Answer»

Explanation:This sharing of electrons allowing atoms to "stick" together is the basis of covalent bonding. There is some intermediate distant, generally a bit longer than 0.1 nm, or if you prefer 100 pm, at which the attractive forces significantly outweigh the repulsive forces and a bond will be formed if both atoms can achieve a completen s2np6 configuration. It is this behavior that Lewis captured in his octet rule. The valence electron configurations of the CONSTITUENT atoms of a covalent compound are important factors in determining its structure, stoichiometry, and properties. For example, chlorine, with seven valence electrons, is one electron short of an octet. If TWO chlorine atoms share their unpaired electrons by making a covalent bond and forming Cl2, they can each complete their valence shell:99cbb09f87af5a4b09dd56499e843e08.jpgEach chlorine atom now has an octet. The electron pair being shared by the atoms is called a bonding pair ; the other three pairs of electrons on each chlorine atom are called lone pairs. Lone pairs are not involved in covalent bonding. If both electrons in a covalent bond come from the same atom, the bond is called a coordinate covalent bond.We can illustrate the formation of a water molecule from two hydrogen atoms and an oxygen atom using Lewis dot symbols:254015a5c4a159aa4e955da701127624.jpgThe structure on the right is the Lewis electron structure, or Lewis structure, for H2O. With two bonding pairs and two lone pairs, the oxygen atom has now completed its octet. Moreover, by sharing a bonding pair with oxygen, each hydrogen atom now has a full valence shell of two electrons. Chemists usually indicate a bonding pair by a single line, as shown here for our two examples:67f67edbdb9eef2f11217fe1ff08c85b.jpgThe following procedure can be used to construct Lewis electron structures for more complex molecules and ions:1. Arrange the atoms to show specific connections. When there is a central atom, it is usually the least electronegative element in the compound. Chemists usually list this central atom first in the chemical formula (as in CCl4 and CO32−, which both have C as the central atom), which is another clue to the compound’s structure. Hydrogen and the halogens are almost ALWAYS connected to only one other atom, so they are usually terminal rather than central.Edit sectionNote the PatternThe central atom is usually the least electronegative element in the molecule or ion; hydrogen and the halogens are usually terminal.2. Determine the total number of valence electrons in the molecule or ion. ADD together the valence electrons from each atom. (Recall from Chapter 2 that the number of valence electrons is indicated by the position of the element in the periodic table.) If the species is a polyatomic ion, remember to add or subtract the number of electrons necessary to give the total charge on the ion. For CO32−, for example, we add two electrons to the total because of the −2 charge.3. Place a bonding pair of electrons between each pair of adjacent atoms to give a single bond. In H2O, for example, there is a bonding pair of electrons between oxygen and each hydrogen.4. BEGINNING with the terminal atoms, add enough electrons to each atom to give each atom an octet (two for hydrogen). These electrons will usually be lone pairs.5. If any electrons are left over, place them on the central atom. We explain in Section 4.6 that some atoms are able to accommodate more than eight electrons.6. If the central atom has fewer electrons than an octet, use lone pairs from terminal atoms to form multiple (double or triple) bonds to the central atom to achieve an octet. This will not change the number of electrons on the terminal atoms.Now let’s apply this procedure to some particular compounds, beginning with one we have already discussed.Edit sectionH2O1. Because H atoms are almost always terminal, the arrangement within the molecule must be HOH.2. Each H atom (group 1) has 1 valence electron, and the O atom (group 16) has 6 valence electrons, for a total of 8 valence electrons.3. Placing one bonding pair of electrons between the O atom and each H atom gives H:O:H, with 4 electrons left over.4. Each H atom has a full valence shell of 2 electrons.5. Adding the remaining 4 electrons to the oxygen (as two lone pairs) gives the following structure:f6d9a24622184ca561822f70eb85e58b.jpgThis is the Lewis structure we drew earlier. Because it gives oxygen an octet and each hydrogen two electrons, we do not need to use step 6.

What happens during fusion?

Answer»

Fusion is the PROCESS that powers the SUN and the stars. It is the reaction in which two ATOMS of hydrogen combine together, or fuse, to form an ATOM of helium. In the process some of the mass of the hydrogen is converted into ENERGY.

48369.

Where does nuclear fusion occur naturally?

Answer»

our sunFusion REACTIONS occur naturally in stars like our SUN, where two hydrogen nuclei fuse together under high temperatures and pressure to form a nucleus of HELIUM. Energy is released as electromagnetic radiation such as light, infra-red radiation and ultra VIOLET radiation , which then travels through space.

Why is mass lost in nuclear fusion?

Answer»

This means that if two low-mass nuclei can be fused together to form a larger nucleus, energy can be released. The larger nucleus has a greater binding energy and LESS mass PER nucleon than the two that combined. THUS mass is destroyed in the FUSION REACTION, and energy is released

Why is fission better than fusion?

Answer»

There are plenty of NUCLEAR fission reactors that actually provide useful energy. ... FUSION, on the other hand, is very difficult. INSTEAD of shooting a NEUTRON at an atom to start the process, you have to get TWO positively charged nuclei close enough together to get them to fuse.Explanation:

48397.

Does fission or fusion require high temperatures?

Answer»

Explanation:Fission Fission occurs when a neutron slams into a larger atom, forcing it to excite and spilt into two smaller atoms—also known as fission products. Additional neutrons are also released that can INITIATE a chain reaction. When each atom splits, a tremendous amount of energy is released.  Uranium and plutonium are most commonly used for fission reactions in nuclear POWER reactors because they are easy to initiate and control.  The energy released by fission in these reactors HEATS water into steam. The steam is used to spin a turbine to produce carbon-free electricity.Fusion   Fusion occurs when two atoms slam together to form a heavier atom, like when two hydrogen atoms fuse to form one HELIUM atom.  This is the same process that powers the sun and creates huge amounts of energy—several times greater than fission. It also doesn’t produce highly RADIOACTIVE fission products.  Fusion reactions are being studied by scientists, but are difficult to sustain for long periods of time because of the tremendous amount of pressure and temperature needed to join the nuclei together.Source: https://www.energy.gov/ne/articles/fission-and-fusion-what-difference

48398.

Why do we not use fusion for the production of electricity?

Answer»

Normally, fusion is not POSSIBLE because the strongly REPULSIVE ELECTROSTATIC forces between the positively charged nuclei prevent them from getting CLOSE enough together to collide and for fusion to occur.

48399.

Can we control nuclear fusion?

Answer»

To maintain a sustained controlled nuclear REACTION, for EVERY 2 or 3 neutrons released, only one must be allowed to strike another URANIUM nucleus.

48400.

Does fission or fusion produce more energy?

Answer»

Elements heavier than Iron produce more energy through fission. Fission is when a large nucleus divides into smaller NUCLEI RELEASING energy. ... So, the ANSWER is fusion produces more energy if it involves light elements and fission produces more energy if it involves HEAVY elements.Explanation:
