C) Au, Cu

In chemistry valence is a measure of the number of bonds formed by an atom of a given element. Valence can be defined as the number of valence bonds[1] a...

Valency: As - 3, 5 Ga - 3 Ge - 2, 4 Pb - 2, 4 Xe - 0 (rarely 1, 2, 4, 6, 8) Rb - 1 Os -...

Oxygen has an oxidation state of minus;1 in peroxides , eg H2O2 or minus;1/2 in superoxides , eg KO2

Since the energy required to remove one electron is called the ionization energy or the ionization potential, the energy required to remove two will be called the double ionization energy...

Nucleon number is the sum of the numbers of protons and neutrons. Therefore, for an unknown atom it will be 29 + 1 = 30. An element that contains one...

Valence electrons are the electrons on the outer shell of each atom. The number of valence electrons is directly related for groups 1-2 and 13-18 (group A). However, the number...

Faraday's law: m=kq= q*M/(F*z); m =n*M=> z=q/(F*n); n =1mol (condition) F - constant= 96 485.333 C/molz=(289500/96485.333*1)=3valency=3
