Max Planck'sNiels Bohr's 1913 quantum MODEL of the atom, which incorporated an explanation of Johannes Rydberg's 1888 formula, Max Planck's 1900 quantum hypothesis, i.e. that atomic energy RADIATORS have DISCRETE energy values (ε = hν), J. J.

i have not UNDERSTAND your QUESTION

The Geiger–Müller tube or G–M tube is the sensing element of the Geiger counter instrument used for the detection of ionizing radiation. It was named after Hans Geiger, who invented the principle in 1908,[1] and Walther Müller, who collaborated with Geiger in developing the technique further in 1928 to PRODUCE a practical tube that could detect a number of different radiation types.[2][3]A complete Geiger counter, with the Geiger-Muller tube mounted in a cylindrical enclosure connected by a cable to the instrument.It is a gaseous ionization detector and uses the Townsend avalanche phenomenon to produce an easily detectable electronic pulse from as little as a single ionising event due to a radiation particle. It is used for the detection of gamma radiation, X-rays, and alpha and beta particles. It can also be adapted to detect neutrons. The tube operates in the "Geiger" region of ion pair generation. This is shown on the accompanying plot for gaseous detectors showing ion current against applied voltage.While it is a robust and INEXPENSIVE detector, the G–M is unable to measure high radiation rates efficiently, has a finite LIFE in high radiation areas and cannot measure incident radiation energy, so no spectral information can be generated and there is no discrimination between radiation types; such as between alpha and beta particles.Explanation:plz mark me as brainliest plz do it FAST and I will FOLLOW you

element of SURPRISE that I have to do that to me and I don't have a aka the people I CARE about me being a LITTLE while and I was LIKE I don't want me there is no longer a slave to the store and I have no c u at the end I use it to message and call the

The salt bridge allows ion migration and maintains ELECTRICAL neutrality in TWO solutions. The salt bridge provides electrical contact between the two solutions and completes the electrical circuit. It prevents the mixing of ELECTRODE solutions.Without the salt bridge, the solution in the anode COMPARTMENT would become positively charged and the solution in the cathode compartment would become negatively charged. This will cause charge imbalance and the electrode reaction would quickly COME to a halt.Explanation: please mark me as brainliest plz do it fast and I will follow you

the nuclear forceExplanation:the force that holds a nucleustogether is the nuclear force, a short- range force between NUCLEONS. At very small separations,the nuclear force is repulsive,KEEPING the PROTONS and neutrons from GETTING to close to one another.PLEASE PUT ME AS BRAINLIEST..

A salt bridge, in ELECTROCHEMISTRY, is a laboratory device used to connect the oxidation and REDUCTION half CELLS of a galvanic cell(voltaic cell), a type of elctrochemical cell. It maintains electrical NEUTRALITY within the internal circuit, preventing the cell from rapidly running its reaction to equilibrium. If no salt bridge were PRESENT, the solution in one half cell would accumulate negative charge and the solution in the other half cell would accumulate positive charge as the reaction proceeded, quickly preventing further reaction, and hence production of electricity.Salt bridge keeps the solutions in two half-cells electrically neutral. It prevents transference or diffusion of the ions from one half-cell to the other.please mark me as brainliest plz do it fast and I will follow you

Friedel-Crafts Alkylation refers to the replacement of an aromatic proton with an alkyl GROUP. This is done through an electrophilic attack on the aromatic ring with the help of a carbocation. The Friedel-Crafts alkylation reaction is a method of GENERATING alkylbenzenes by using alkyl halides as reactants.HOPE IT HELPFUL FOR U (◍•ᴗ•◍)❤(ʘᴗʘ✿)(✷‿✷)EXPLANATION:MARK AS BRAINLIEST ✌️❤️ (◕ᴗ◕✿)(ʘᴗʘ✿)(✷‿✷)(◍•ᴗ•◍)❤♥╣[-_-]╠♥

Positively CHARGED ions, or cations, MOVE TOWARD the electron-providing CATHODE, which is negative; negatively charged ions, or anions, move toward the positive anode. You may have noticed that this is the OPPOSITE of a galvanic cell, where the anode is negative and the cathode is positive.

The ACIDIC COMPONENT reacting with a basic component to give a salt with release of water is said to be neutralization reaction. As the salt formation takes PLACE, no more reactants can be added to the reaction.Explanation:Hope this MAY help you....

D, is the STRONG ACID .....

Benzenesulfonic acidExplanation:Sulfonation of benzene includes an ELECTROPHILIC substitution reaction that OCCURS between benzene and sulfuric acid. There are two equivalent ways of sulfonating benzene: The first way involves heating of benzene under reflux of concentrated FUMING sulfuric acid for several HOURS at 40°C. The product formed is benzenesulfonic acid.

1. The law of the conservation of mass, in which mass before REACTION has to equal mass after reaction. The law of constant proportions, in which the ratio mass for the same compound is constant. The law of multiple proportions, in which multiple elements can combine with each other in multiple ratios; and finally.2.The law of constant proportions states that chemical COMPOUNDS are made up of elements that are present in a fixed ratio by mass. ... For example, in a nitrogen dioxide (NO2) MOLECULE, the ratio of the number of nitrogen and oxygen atoms is 1:2 but the mass ratio is 14:32 (or 7:16).3. In chemistry, the law of definite proportion, sometimes called Proust's law, or law of constant composition states that a given chemical compound always CONTAINS its component elements in fixed ratio (by mass) and does not depend on its source and method of preparation.HOPE IT HELPS U &please mark me brainliest

n: 15Which statement is true for an ELECTROCHEMICALCELL?O OXIDATION OCCURS at both the ANODE and cathode,✔️O Reduction occurs at both the anode and cathodeO Oxidation occurs at the anode ONLYO Reduction occurs at the anode onlyInvalid Question

In CHEMISTRY, the unit is the amount of ENERGY required for all of the atoms in a mole of SUBSTANCE to lose one electron each: molar ionization energy or APPROXIMATELY enthalpy, expressed as kilojoules per mole (kJ/mol) or kilocalories per mole (kcal/mol).EXPLANATION:Hope it helps you

A galvanic cell consists of two half-cells, such that the electrode of one half-cell is COMPOSED of metal A, and the electrode of the other half-cell is composed of metal B; the redox REACTIONS for the two separate half-cells are thus: An+ + ne− ⇌ A. Bm+ + me− ⇌ B.Explanation:PLEASE mark me BRAINLIST

two elementsThere are seven periods in the periodic table, with each one beginning at the far left. A NEW period begins when a new principal energy level begins filling with electrons. Period 1 has only two elements (hydrogen and helium), while periods 2 and 3 have 8 elements. Periods 4 and 5 have 18 elements.Explanation:Hope it HELPS you

Many CHEMICAL reactions are reversible; that is, the PRODUCTS of the REACTION can COMBINE to re-form the reactants. An example of a reversible reaction is that of hydrogen with IODINE to form hydrogen iodide:H2(g) + I2(g) 2 HI(g)
