The decrease in atomic radii across a period from group 1 to group 14 is mainly due to increasing effective nuclear charge. As you move across a period, the number of protons in the nucleus increases, pulling the electrons closer to the nucleus. This results in a stronger attraction between the nucleus and the electrons, leading to a decrease in atomic size.

Atomic radius increases down a group.

This happens because of the addition of one more shell.

Does elements on the periodic table decrease in atomic size when you move across a period from left to right and when you move down a group?

1. In a period is a trend of decrease from left to right but it is not absolute.2. In a group the atomic radius increase moving down.


How does the atomic radius change from the left to the right horizontal row in the periodic table?

from left to right the atomic radius decreases as the electrons that get added are added in the same shell as they are in the same period. the shielding effect remains constant but the proton number increases which inturn increases the effective nuclear pull on the electrons bringing the electrons closer to the nuclei hence decreasing the radius of the atom


What trend in atomic radii do periods 3 through 6 have in common in the periodic table?

Atomic radii generally decrease across periods 3 through 6 in the periodic table. This is because as you move from left to right across a period, the number of protons and electrons increases, leading to stronger attraction between the nucleus and the electrons, pulling the outer electrons closer to the nucleus, thus decreasing the atomic radius.

What is the general trend in densities for period 2?

The general trend in densities for period 2 elements of the periodic table is that densities increase from left to right. This is because elements in period 2 have increasing atomic numbers, leading to an increase in atomic mass and a decrease in atomic volume, resulting in higher densities.

What happens to the energy needed to remove an electron as the atomic number increases down a family?

As the atomic number increases down a family, the energy needed to remove an electron decreases. This is because electrons are further from the nucleus with increasing atomic number, leading to weaker attraction and therefore less energy required to remove an electron.
