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.

What element has the smallest atomic radius?
Helium usually is listed with the smallest atomic radius when calculated. Hydrogen however has a smaller van der Waals radius The protium isotope of hydrogen has the smallest nucleus radius. It is 1.6 fm
How can you use the word atomic radius in a sentence?
Please tell me your atomicnumber.You just did 'use atomic number in a sentence' by putting this question on-screen.You could even read the above question and answers aloud, and you will have done it again.I just couldn't believe my eyes when I realized that an atomic number is revealed by the number of protons in the nucleus of an atom!"What is your atomic number?" is NOT a good pick-up line, unless you are speaking to a scientifically-minded person.The atomic number of Helium is 2."The atomic number of Sulfur is 16."(Note that atomic number means the number of protons in the atom, that's why the term proton number is interchangeable with atomic number.)See the related Wikipedia link listed below for more information:
Given any two elements within a group is the element with the larger atomic number likely to have a larger or smaller atomic radius than the other element?
The atomic radius decreases across a period from left to right and increases down in a given group. That means that since the lower the element is in a group, the larger the atomic radius will be. The atoms with the largest atomic radii are located in Group I and are at the bottom of groups.
What is the atomic radius of aluminum?
Gallium is a non metal element. Atomic mass of it is 70.
What is the atomic radius of iron?
The calculated atomic radius of chromium is 166 pm; for more details see the link below.
What happens to the atomic radius as you go down the metals What happens to the reactivity?
Examples for the groups I an II of the periodic table:- the atomic radius grows from top to bottom- the electronegativity descends from top to bottom
When atoms gains electrons what happens to the atomic radius?
The negative ionic radius is larger than the neutral atomic radius
What happens to the atomic radius as you from the bottom to the top of the periodic table?
The atomic radius decreases.
What happens to an atomic radius when an electrons is lost?
The positive ionic radius is smaller than the neutral atomic radius
What happens to the atomic radius when an electron is gained?
The negative ionic radius is larger than the neutral atomic radius
How does the ionic radius of a nonmetal compare with its atomic radius?
in the case of non-metals, the anions are formed by the addition of electrons. So the ionic radius is larger than that of the atomic radius
What do forces have to do with atomic radius of alkali metals?
they are bigger they are bigger
What is the process that results in the increase of atomic number?
The number of energy levels increase within a group. Therefor the atomic radius increases. So the atomic volume also increases.The atomic radius also increases in a group.For metals, reactivity increases down the group. For non-metals, reactivity decreases down a group.
What group of elements have members of the smallest atomic radii for a given period?
Noble gases have the smallest atomic radius.
Which of the following decrease as you go from left to right on the periodic table?
The atomic radius decreases as you go from left to right. or atomic radius cation radius && anion radius -barbie=]
What happens to the atomic radius when an electron is lost?
the positive ionic radius is smaller than the neutral atomic radius
