Question

Calculate block, period and group no. of an element with atomic no. 25.

Answer 1

Explanation:

1. For s-block elements , group number is equal to the number of valence electrons.
2. For s-block elements , group number is equal to the number of valence electrons.For p-block elements ,group number is equal to 10+number of electrons electrons in the Valence shell .
3. For s-block elements , group number is equal to the number of valence electrons.For p-block elements ,group number is equal to 10+number of electrons electrons in the Valence shell .For d-block elements group number is equal to the number of electrons in a (n-1) d subshell + the number of electrons in Valence shell
