Why covalent bond not formed when electronegativity diffrence is greater than zero?

Answer»

ectronegativity DIFFERENCE is greater than zero, one element is electropositive and one element is electronegative. So, it is CLEARLY more convenient and stable to FORM BONDS by transfer of electrons instead of sharing of electrons. So, IONIC bonds are formed

Write a brief note on quantum numbers . send me large answers pls​

Answer»

Quantum numbers can be used to describe the trajectory and the movement of an electron in an atom. The quantum numbers of all the ELECTRONS in a given atom, when combined, must comply with the Schrodinger equation.What are Quantum Numbers?The set of numbers used to describe the position and energy of the electron in an atom are called quantum numbers. There are four quantum numbers, namely, principal, azimuthal, magnetic and SPIN quantum numbers.The values of the conserved quantities of a quantum system are given by quantum numbers. Electronic quantum numbers (the quantum numbers describing electrons) can be DEFINED as a group of NUMERICAL values which provide solutions that are acceptable by the Schrodinger wave equation for hydrogen atoms.Four quantum numbers can be used to completely describe all the attributes of a given electron belonging to an atom, these are:Principal quantum NUMBER, denoted by n.Orbital angular momentum quantum number (or azimuthal quantum number), denoted by l.Magnetic quantum number, denoted by ml.The electron spin quantum number, denoted by ms.

A solution contains 10 g of sugar in 140 g of water.what is the concentration in terms of mass by mass percentage of the solution A)7.1% B)8.2% C) 6.6% D)7.7%

Answer»

→Mass of sugar (solute) = 10g→Mass of WATER (solvent) = 140gTo find:-→Concentration of the solution (mass/mass %)Solution:-Here, mass of solute and mass of solvent are given. So,firstly let's calculate the TOTAL mass of the solution. It can be calculated as follows:-Mass of solution:-= Mass of solute + Mass of solvent= (10+140) g= 150gHence,we have GOT the mass of the solution as 150g.Now,let's calculate the concentration of the solution.Concentration of a solution:-=Mass of solute/Mass of solution × 100= 10/150×100= 100/15= 6.6%. (approximately)THUS,concentration of the solution in terms of mass by mass percentage is 6.6% and hence CORRECT option is (C).

Comment on the similarities of hydrogen with alkaline metals and halogens​

Answer»

However, it has non-metallic character, is a gas (while alkali metals are solid) and cannot LOSE its valence electron. Hydrogen is ALSO similar to halogens, since it forms diatomic molecules (H2, same as halogens- Cl2, etc.), needs one more electron to completely fill its outermost shell, etc.Explanation:Elements such as fluorine, chlorine, bromine, iodine, and astatine belong to Group 17, the halogen group. At room TEMPERATURE fluorine is a yellow gas, chlorine is a pale green gas, bromine is a red liquid, and iodine is a purple solid. Astatine is a radioactive element, and exists in nature only in small amounts. All the halogens exist as diatomic molecules. They have high IONIZATION energies and form the most electronegative group of elements. Their electron configuration, ns2np5, allows them to easily react with Group 1 and 2 metals; each halogen tends to pick up one electron, and the Group 1 and Group 2 elements each tend to lose one or two electrons, respectively. Halogens therefore react most vigorously with Group 1 and Group 2 metals of all main group elements.From a standard reduction potential table, it is determined that iodine and bromine cannot oxidize water to oxygen because they have smaller reduction potentials than oxygen. Thus, iodine and bromine do not react with water. However, fluorine and chlorine have larger reduction potentials, and can oxidize water.
