Atomic radius increases down the group due to increase in no.of orbits around the nucleus.
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.
As you go down group atomic radii increase
The atomic radius increases.
It gt smaler
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.
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
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.
decreases
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.
The atomic radius decrease, with several exceptions in periods 6 and 5.
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.
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.
As you move across the periodic table from left to right (across a period), the atomic radius of the elements tends to decrease.
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
atomic size decreases across a period
The atomic number increases as one go across a period.
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.
across a period, the atomic size decreases as the effective nuclear charge increases.
It decreases.
Atomic radius usually decreases from left to right across a period of the periodic table.
