Question

as
we moving from left to right along
a period, whad changes may occare for
the following?
(a) Lonisation energe
(6) eletronegativity​

Answer 1

Electronegativity

On moving from left to right across a period, electronegativity increases.

With increase in atomic number, the nuclear charge increases but the number of shells in the atoms of all the elements in a period remains the same. The nuclear attraction of the outermost electron increases. Hence, tendency to attract shared pair of electrons increases from left to right in a period.

Ionisation potential

On moving from left to right across a period, ionisation potential increases.

With increase in atomic number, the nuclear charge increases but the number of shells in the atoms of all the elements in a period remains the same. The nuclear attraction of the outermost electron increases due to which ionisation potential increases.
