"Transition metal elements" are the type of element which have atomic radii which remain relatively constant across a period.
Periods refer to the horizontal lines of the periodic table. Each period represents the sequential occupation of an atom's valence shell orbitals, also with longer periods representing the employment of an atom's d subshell orbitals.
As the atomic number rises, more electrons, as well as protons, are present, increasing attraction over time, which drives the atomic radius to shrink over time.
Therefore, "Transition metal elements" are the type of element which have atomic radii which remain relatively constant across a period.

When atoms react they form a chemical bond which is defined as the force of attraction that holds atoms together. It can be covalent bonding, ionic bonding or metallic type of bonding. These bonds are what atoms in a compound hold together.
