What happens to the size of atoms in p-block elements when we move from left to right in the same period?
a) Size does not change
b) Size increases then decreases
c) Size increases
d) Size decreases
Answer : d) Size decreases
Explanation :
When we moves from left to right throughout same period in periodic table the no.of electrons are increases and increase in no.of electrons increases the positive charges inside the nuclear. The overall effective nuclear charge rises as result. As results the decrease in size of elements in same period in periodic table.
d) Size decreases
