Question

1. this simulation shows atoms as a nucleus surrounded by an electron cloud. the distance from the nucleus to the edge of the electron cloud is the atomic radius. this is a measure of the size of an atom. determine what happens to the atomic radius as you go from left to right in a period. i need a hint the atomic radius decreases as you go from left to right in a period. the atomic radius increases as you go from left to right in a period. the atomic radius stays the same as you go from left to right in a period.

Explanation:

As you move from left to right across a period in the periodic table, the number of protons in the nucleus increases (nuclear charge increases). While the number of electron shells remains the same. The increased positive charge in the nucleus attracts the electrons more strongly, pulling them closer to the nucleus. This results in a decrease in the atomic radius.

Answer:

The atomic radius decreases as you go from left to right in a period.
