No, the radius decreases. Electrons, being negative, repel each other. The more electrons there are, the farther away they have to get from each other. The fewer there are, the less total force there is, and the closer they can be.

Does a metal have a greater atomic radius or ionic radius?
A metal will tend to lose electrons and hence the atomic radius is higher than the ionic radius.
When atoms gains electrons what happens to the atomic radius?
The negative ionic radius is larger than the neutral atomic radius
When metals become ions what happens to their atomic radius?
Metals generally become cations and thus lose electrons and their atomic radius shrinks. This is because the metals will lose a shell of electrons and the nucleus' pull on the electrons will become more concentrated, pulling them closer.
Why does the atomic radius change as electrons are added to a shell?
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)
Why does the atomic radius increase as you go down the familY?
Because you have more electrons in the atom
When does the atomic radius of an atom increase?
the radius of an atom gets larger when moving left to right across the Periodic Table because elements gain protons and electrons- the increase in charge brings the atom radius in
Why does the size of the elements increase down a group?
The atomic numbers of the elements down a group increase. this means, more electrons. More electrons mean more shells. More shells mean larger radius. Larger radius is nothing but larger size. Thus, the number of electrons or shells is the reason why the size of the atom of elements increase down the group.
How can you can increase or decrease the energy possessed by electrons?
Electrons can absorb photons and gain energy, and they can emit photons and lose energy.
Why the atomic radius increase in column of periodic table?
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.
Why are size of cations always smaller and size of anions always bigger than the corresponding atom?
anions always gain extra electrons casing the ionic radius to increase but cations remove electrons causing the ionic radius to decrease .therefore anionic radius is greater than cationic radius
When does the radius of an atom decreases or increases?
the radius of an atom gets larger when moving left to right across the periodic table because elements gain protons and electrons- the increase in charge brings the atom radius in
How does the presence of core electrons affect the atomic radius of elements?
When there is an anion (negative charge) the radius will be larger because it is more full whereas it will be smaller if it is a positive charge because of less electrons. ex largest to smallest radius (K-,K, K+)
