Question

How does electronic configuration of atoms change in period within increase in the atomic number?

Answer 1

Electronic configuration of atoms change in period within increase in the atomic number:

Explanation:

• In a 'period' with increase in 'atomic number' from left to right, the 'electronic configuration' changes by keeping the shells the same in the period and the electrons

• in the outermost shells keeps on increasing while going from 'left to rightmost in a period'.

• This is because while moving from left end to right end in a period, the atomic number keeps on increases by 1 and thereby the number of electrons also increases by 1.

• This leads to the increase in the electrons present in the 'outermost shell' of the electronic configuration in the period while the shells remain the same.
