what is ionization energy?
the energy needed to remove the outermost, or highest energy, electron from a neutral atom

what is the difference between the radii of atoms and the radii of ions?
Atomic radius is the distance from the atomic nucleus to the outermost electron of an atom.The ionic radius is one half the distance between two atoms that are just touching each other.

What are valence electrons?
Electrons of an atom that have the highest energy level.

400
based on the electron configuration of bromine: [Ar] 3d10 4s2 4p5, how many valence electrons does it contain?
7
400
The 1)______ ______ refers to the distance between an atom's nucleus and its 2)_______ ________. 3)________________ is a measure of how strongly atoms attract bonding electrons to themselves.
1)atomic radius 2)valence electrons 3)electronegativity
500
If an atom has high ionization energy, is it more or less likely to lose an electron? Why?
Less likely because high ionization energy means it takes more energy to remove an electron, so it is less likely to happen.
500
which atom has lower ionization energy, Be or N?
N
500
This happens to the hold as the distance between the electrons and the nucleus increases.
it becomes weaker
