No. Atomic radii shrink.
Protons never shrink.
they increase left to right
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

ionization energy
Both the atomic number and atomic mass. among many other things. They increase the atomic number because the atomic number IS the number of protons in an atom. They increase the atomic mass because the atomic mass is the number of protons + neutrons in an atom. Basically the main two things..
The number of protons and electrons increase by one from left to right.
more metallic moving from left to right
the number of collecting protons gets bigger.
As a general rule, when moving left to right on the periodic table the atomic radius decreases due to increasing electromagnetic attraction of the nucleus to the electrons.
The mass of an element is the sum of the protons and neutrons in an atom. It is usually listed right on the periodic table.
From left to right, then top to bottom we have increasing numbers of protons (and in whole atoms also electrons).
Protons increases by one as we move from one element to other, left to right.
