You need to know what each component is when looking at a single block on the periodic table.
Using the periodic table information for oxygen, match each item in the box to its appropriate identifying term.

| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
8 | arrow_right_alt | symbol |
15.9994 | arrow_right_alt | element name |
O | arrow_right_alt | atomic mass |
oxygen | arrow_right_alt | atomic number |
There are also some essential rules to know for determining the atomic structure.
Match the strategy we can use for determining the amount of each subatomic particle (protein, neutron, or electron) with the strategy we should use to calculate it.1
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
# of protons = | arrow_right_alt | the number of protons |
mass # = | arrow_right_alt | the # of electrons |
atomic # = | arrow_right_alt | protons + neutrons |
