The angular momentum of each shell can be calculated by the formula. mvr = (nh/2π) Definition of Subshell All the electrons having the same shall do not have the same energy. Based on the …

Characteristics of Valence Electron Electrons are involved in the chemical bonding and reactions of the atom. It is said to occupy orbitals in an atom. The number of valence electrons of an …

What is the importance of Valency? The importance of valence: when two atoms react, their outer shell first comes into contact and it is, therefore, the outer shell electron that is normally …

An ion, atom, or a molecule containing an unpaired valence electron is called a free radical. These species disobey the octet rule. However, they are very unstable and tend to spontaneously …

The Valence Shell Electron Pair Repulsion Theory, abbreviated as VSEPR theory, is based on the premise that there is a repulsion between the pairs of valence electrons in all atoms, and the …

The presence of many unpaired electrons in the valence shell of an atom enables it to form multiple bonds with other atoms. The paired electrons present in the valence shell do not take …

Writing Electron Configurations Shells The maximum number of electrons that can be accommodated in a shell is based on the principal quantum number (n). It is represented by …

What is the cause of variable valency? The electrons which are present in an atom’s outermost shell are called valence electrons. So one or more electrons from the core’s outermost shell …

By the mutual sharing of electrons, each atom attains an octet configuration in its valence shell. Electron dot structures of covalent molecules are written with respect to the octet rule. …

The number of electrons gained, lost or shared so as to complete the octet of electrons in the outermost shell, gives us the combining capacity of the element, i.e. the valency. Outermost …
