As you move down a GROUP on the periodic table the atomic radius get bigger. This is because ____________.
The atoms have more neutrons in the nucleus.
The atoms have more protons in the nucleus.
The atoms have more energy levels for the electrons
The atoms have greater repulsion forces between the protons and electrons
As you move across a period on the periodic table the atomic radius tend to get smaller because, ______________.
the atoms have more mass making them heavier.
more neutrons, making the nucleus bigger.
the atoms have more protons, pulling the electrons closer.
the atoms have less energy levels for the electrons to occupy.

As you move across a period on the periodic table the ionization energy tend to increase because, ______________.
the atoms have more mass making them heavier so it is harder to remove the electrons because of this increased mass.
the atoms have more protons in the nucleus making a stronger attraction to the electrons.
the atoms have more neutrons, making the nucleus bigger so they want their electrons more.
the atoms have more energy levels for the electrons to occupy so they don't want to leave the atom.
As you move DOWN a group on the periodic table the ionization energy tend to decrease because, ______________.
the atoms have more mass making them heavier so it is harder to remove the electrons because of this increased mass.
the atoms have more protons in the nucleus making a stronger attraction to the electrons making it harder to remove them.
the atoms have more neutrons, making the nucleus bigger so they attract their electrons more making it easier to remove them.
the atoms have more energy levels and the electrons that are being removed are further away so there is less attraction making it easier to remove them.
Which element has a greater ATOMIC RADIUS, helium (He) or xenon (Xe)?
helium
xenon
Which element has a greater IONIZATION ENERGY, sulfur (S) or chlorine (Cl)?
sulfur
chlorine
