Which of these best explains the reasoning behind the trend in radius as you go across a period?
As you go across a period, more energy levels are added, which shrinks the atom.
The added electrons in the nucleus give the atom a negative charge, which shrinks the atom.
The added protons in the nucleus pull the electrons closer to them, which shrinks the atom.
All of the above
As you move down the periodic table atoms get ________. This is because ____________.
Bigger; the electrons are in higher energy levels
Bigger; the electrons are in lower energy levels.

Which ion has the smaller radius?
Ba
Ba+1
Which is larger:
P or P-3 ?
P because it is the neutral atom.
P-3 because it lost 3 electrons.
P-3 because it gained 3 electrons.
They are the same size since they are both P.
Which is the larger atom: F-1, Cl-1, Br-1?
F-1
Cl-1
Br-1
they are all the same size since they are all anions
