What trend in atomic radius occurs as you move from left to right across a period in the periodic table?

The atomic radius increases because the nuclear charge decreases

The atomic radius decreases because the nuclear charge increases

The atomic radius remains constant because the number of energy levels remains the same

The atomic radius increases because the number of neutrons increases
