Question

Elements belonging to same group have similar properties.
Same groups after the difference of either 2 or 8 or 18 or 32 in the atomic number
and having similar valence shell electronic configuration have similar properties is it true​

Answer 1

Hi,

here u go with the answer....

Valency of an element determines its chemical reactivity.

Therefore, for all elements belonging to a particular group in the periodic table, the number of electrons in the outermost shell, that is the valence electrons will be the same.

Hence, all the element in that group will show the same chemical reactivity. They will react with different elements in the same way and the molecular formula of their compounds will be similar.

Hence, they have the same chemical properties.
