Please tell me the number of the largest atom?

in group 2 and explain why

Answer:
Radium
atomic number 88

The largest atom is usually located at the bottom of the group.
infinity
you cant tell because you can have element with hgher atomic # then their is in your periodic table
but they just dont exist because they have very small half life
Ba and Ra both have atomic radius of 215

Note the Lanthanide contraction means the atom further down on the periodic table is not actually as big as expected (due to a shielding effect).
