Low ionization energies
Metals generally have low ionization energies. This implies that the valence electrons of metal atoms are not strongly held by the nucleus. Valence electrons can move freely out of the influence of their kernels (atomic orbit/structure minus valence..
Solution:
Cl - 17 : 2, 8, 7Valency = 8 - Number of valence electrons= 8 - 7..
Variation along the period
The number of valence electrons increase from left to right in a period. So, the valency of the elements first increase from 1 to 4 and then decreases to zer..
Need for Bonding
Chemical bonding is like a glue that binds atoms together. And what goes into making that glue? Only electrons. Not all electrons make up the glue, it is only the valence electrons. Valence electrons are the outermost electronsh..
Example
Cl - 17 : 2, 8, 7 Valency = 8 - Number of valence electrons = 8 - 7 ..
Cause of periodicity of elements
The modern periodic table is based on the electronic configuration of the elements. The properties of an element are determined largely by the electrons in its outermost or valence shell. Valence electrons interact with other atoms and take part in..

Where duplet is formed?
A hydrogen atom has only one electron in its valence shell. It needs one more electron to fill its valence shell. The completed shell has the electronic arrangement of the noble gas helium, yet an octet is not completed. However we still get a stab..
Quantum Theory of Covalent Bond
Although the Lewis structures give an idea of the valence electrons around the atom, in reality it does not precisely locate the position of the electrons in the chemical bond. The behaviour of electrons in molecules and compounds is made by the va..
General Characteristics of Periods
1. Valence shell electrons The valence shell electrons increase form one to seven as we move from left to right in a period. 2. Valency The valency of the elements with respect to hydrogen, increases form 1 to 4 and then falls from 4 to 1 ..
