It increases.
One half the distance between nuclei.
The atomic radii is an estimation of the radius of an atom. The value of the atomic radii is based off an approximation of the distance from the atom's nucleus to the edge of the atom's electron cloud.
Argon is the atom that has the smallest radius in Period 3. As you go cross Period 3 from left to right, the atomic radii of the elements decrease. The elements in Period 3 from left to right begin with sodium and ends with argon.
Atomic radius is the measure from the middle of an atom to the outter edge. Usually mesured between two atom. Measure from the middle of one atom to the middle of another and then divide by two.
Ti
The diameter of an atom varies between 62 and 520 pm, depending on on the specific type of atom.
Half the distance between the two nuclei
Atomic radius is simply the radius of the atom, an indication of the atom's volume.
Scandium empirical atom radius: 160 pm Scandium calculated atom radius: 184 pm
The radius of an anion is bigger than the radius of a neutral atom.
