Question

As you move from left to right along the horizontal rows in the periodic table, the number of ______ in the nucleus increase by one.​

Answer 1

Answer:

cytoplasm is move right

Answer 2

Atomic radius

When you move from left to right across a period, or row, of the periodic table, atomic radius decreases as more and more electrons are added to same energy level.

This increases the effective nuclear charge due to poor shielding.

The valence electrons are more strongly attracted by the nucleus.

Due to this, the atomic radius decreases. However, ionization energy, electron affinity and the number of valence electrons increases from left to right across a period.

Hence, the correct option is E.
