The largest atoms on the periodic table are the heavier alkali metals.
The elements with the smallest atomic radii are found in the top of the P block of the periodic table. Helium (He) has the smallest atomic radius. Francium, on the other side of the periodic table (very bottom of the S block), has the largest atomic radius.
From smallest to largest atomic number, Helium, Neon, Argon, Krypton, Xenon, Radon.
Atoms are the things that make up the world, so they are found everwhere.
On the left side of the periodic table.
yes
group 1
its when too atoms are alike
