This is because of the fact atomic radius is the distance of the outermost electron to the nucleus thus as more electrons are added the distance increase (which cause atomic radius to change)
the atomic radius increases down the periodic table as the number of shell (or energy level) increases.
Atomic center is the center of the atom, also called as Nucleus. Atomic Radius is the distance between the center of the nucleus and outermost shell of the atom. It is nearly about 1.2 * 10-10 m.
Down a group, the atomic radius increases as the number of shells or energy levels increases.
As you go down the columns of the periodic table the number of protons (and electrons) in the element increase. As the atomic number increases, so does the radius at each electron shell.

Carbon can either have a +4 or a -4 charge because it has four electrons in it's outermost electron level. It would be the same for it to take or remove electrons. This is very rare though, Carbon would most likely share electrons.

Going across a row in the peiodic table, the atoms have more protons and electrons causing a stronger attractive force, pulling the electrons closer to the nucleus, making the atomic radius decrease. As a new shell is added ( next row down) the atomic radius increases
Bromine has a SMALLER atomic radius because it has one more electron shell than Iodine. On the periodic table, atomic radius of an atom decreases across a period and increases down a group. Since Bromine and Iodine are in the same group, you know Bromine has a smaller atomic radius because it is in a lower period.
As you go down the columns of the periodic table the number of protons (and electrons) in the element increase. As the atomic number increases, so does the radius at each electron shell.
The negative ionic radius is larger than the neutral 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 doesn't mean much in how an atom interacts with another. The valence shell (outer most electron orbit) dictates whether or not atoms will form compounds
