- 8What is the charge on an electron?Electrons have a negative charge (-1)
- 9What is the charge on a protonProtons have a positive charge (+!)
- 10What is the charge on a neutron?Neutrons are neutral and have no charge (0)
- 11Which group are these elements found in and how can you tell?They are all in group 1 because they have one electron in the outer shell.
- 12Which group are these elements found n ?They are found in group 0 because the full outer shell is full.
- 13which group and period is this element found?This element is found in group 4 (it has 4 electrons in the outer shell) and period 2 (it has 2 shells.
- 14Which group and period is sodium found it?It is in group 1 ( it has one electron in the outer shell).
It is in period 3 ( it has 3 shells).
- 15What is the name of the top number? What does it show?The top number is called the
ATOMIC MASS.
It shows that lithium has 7 protons AND neutrons in the nucleus.
- 16What is the name given the bottom number? What does it show?The bottom number is the
ATOMIC NUMBER.
It shows the number of PROTONS in an atom.
