Cl - 17 : 2, 8, 7Valency = 8 - Number of valence electrons= 8 - 7..

Nitrogen has 5 electrons in its valence shell. It has a valency of 3 with respect to hydrogen and a valency upto 5 with respect to oxyge..

Members of this group have five electrons in their valence shel..

Cl - 17 : 2, 8, 7 Valency = 8 - Number of valence electrons = 8 - 7 ..

Members of the same group have similar electronic configuration of the valence shell and thus show same valency..

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 f..

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 electrons). Thus, ..

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 all chemical reactions, while..

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 par..

Oxygen and sulphur belong to group VI A. Oxygen shows a valency of -2, while sulphur shows a valency of -2, +4 and +..
