- 10. Multiple Choice
Which of the following reasons explains why there is a decimal for most atomic masses?
The mass of one atom can have a fraction.
Since electrons are very small mass they only add a little bit, usually only a decimals worth.
It is the average mass of all the potential isotopes of an atom.
Neutrons have a mass of 1.1 meaning that fractions are common.
- 11. Multiple Choice
Which of the following is true of atomic radius?
The radius is mainly due to how large an atom's nucleus is.
The radius is mainly due to the size of the electron cloud.
The atomic radius is a way we measure the mass of an atom.
Neutrons account for the majority of an atom's radius.

atomic energy
ionization energy
ionic energy
electron energy
- 13. Multiple Choice
What is the relationship between electronegativity and atomic radius
Larger radius=Larger electronegativity
Smaller Radius= Smaller electronegativity
These are not related
Smaller Radius= Higher electronegativity
