Decreases. Look at the images under atomic radius, on wikipedia.
The atomic radius of gallium is about 135 picometers. In the periodic table, gallium has a larger atomic radius compared to elements to its left and a smaller atomic radius compared to elements to its right.
The atomic radius of iodine is larger than the atomic radius of potassium. This is because as you move down a group in the periodic table, atomic size increases due to the addition of more electron shells. Iodine is located below potassium in the periodic table, hence it has a larger atomic radius.
Silicon has a larger atomic radius than bromine. This is because as you move down a group on the periodic table, atomic radius tends to increase. Bromine is located further to the right on the periodic table and has a smaller atomic radius compared to silicon.
Lead (Pb) has a greater atomic radius than germanium (Ge) because atomic radius generally increases down a group in the periodic table. Lead is located below germanium in the periodic table, so it has more electron shells and a larger atomic radius.
The atomic radius of manganese is about 127 picometers. In the periodic table, manganese has a smaller atomic radius compared to elements in the same period but larger than elements in the same group.
The larger the highest energy level, the larger the atomic radius.
the larger the highest energy level number, the larger the atomic radius (Apex)
The larger the highest energy level, the larger the atomic radius.
the atomic radius decreses from left to right in periodic table due to increase in the number of succesive element the electrons of the outermost shell are more attracted towards nucleus and the atomic radius or atomic size decreases.
The atomic radius increases down a column in the periodic table because as you move from top to bottom, each element has an additional energy level or shell of electrons. This increase in electron shells results in a larger average distance between the nucleus and the outermost electrons, leading to a larger atomic radius.
In the group 2 (IUPAC name) of the periodic table the atomic radius increase from beryllium to radium.
As a general rule, when moving left to right on the periodic table the atomic radius decreases due to increasing electromagnetic attraction of the nucleus to the electrons.
Down a group, the atomic radius increases as the number of shells or energy levels increases.
The atomic radius decreases.
The atomic radius of gallium is about 135 picometers. In the periodic table, gallium has a larger atomic radius compared to elements to its left and a smaller atomic radius compared to elements to its right.
The atomic radius generally increases as you move down a column in the periodic table. This is because each successive element has an additional energy level, leading to larger orbits for the electrons and an overall increase in atomic size.
The atomic radius decreases.
