As the atomic number increases atomic size increases in a group, while it decreases in a period. Give reasons. 

As atomic number increases, atomic size increases in a group and decreases along a period . Give reasons for this behaviour.

As atomic number increases, atomic size increases in a group and decreases along a period . Give reasons for this behaviour.

As the atomic number of halogens increases down the group, the halonges

The atomic radius decreases in a period due to

In a period from left to right A) nuclear charge increases B) effective nuclear charge increases C) atomic size decreases D) Ionisation potential increases Correct among the above are

The atomic size in a period from left to right.

Element with the least atomic size.

The following are some statements about periodic properties i) Atomic size decreases from left to right in a period ii) The EA of 2nd element in VA, VIA, VIIA are greater than the first element iii) Acidic nature of oxides decreases and basic nature of oxides of elements increases down the group
