Question

on moving from left to right in a period table the size of the stom _________.


Mr rider 46​

Answer 1

Explanation:

Experiments have shown that the first case is what happens: the increase in nuclear charge overcomes the repulsion between the additional electrons in the valence level. Therefore, the size of atoms decreases as one moves across a period from left to right in the periodic table.

Answer 2

Answer:

Decreases

Explanation:

On moving from left to right in a period, the atomic size decreases as the atomic number (i.e., the number of protons and electrons) increases but the number of shells remain the same.

Therefore, the force of attraction between the nucleus and the outermost shell of electrons (effective nuclear charge) increases, thus leading to a decrease in the size.
