Question

As we move along the period from left to right the atomic size of elements *
1 point
A) increases
B) does not change
C) decreases
D) increases first and then decreases​

Answer 1

Answer:

B) decreases

Explanation:

The atomic size is the distance from the nucleus of the atom to the outermost shell.

This atomic size decreases as we go across a period i.e when we go from left to right.

For example:

In the second group, Lithium (Li) has some atomic size. When we compare it to the atom of Neon, Neon would have a very small atomic size.

So, atomic size decreases as we move from left to right.

Atomic size increases as we go down a group.
