What Are Ions?
IONS Bromine Can Make
Bromine can make ions of -1, +5, and +7. An ion is basically an element with a charge. To become an ion, an element has to gain or loose electrons. If it gains electrons, it receives a negative charge because it then has more electrons than protons. This is known as an anion. If it looses electrons, it receives a positive charge because it has more protons than electrons. This is known as a cation.
