Describe the trend of Atomic Radius down a group and across a period?

What is Atomic Radius increases down a group and decreases across a period?

300

Which particle is larger in the atom/ion pair; Ca2+ or S2-?

S2- is larger

Both have the same number of electrons, but Ca2+ has more protons pulling on less than the usual number of electrons, so they can put them harder.
