Ionic Bonding
- Ions are electronically charged particles
formed when atoms lose or gain electrons
- This loss or gain leaves a complete highest energy level, so the
electronic structure of an ion is the same as that of a noble gas
- This loss or gain leaves a complete highest energy level, so the
electronic structure of an ion is the same as that of a noble gas
- Metal atoms and non-metal atoms go in
opposite directions when they ionise
- Metal atoms - lose the electron, or electrons, in their highest
energy level and become POSITIVELY charged ions
- Non-metal atoms - gain an electron, or electrons,
from other atom become negatively charged ions
- Metal atoms - lose the electron, or electrons, in their highest
energy level and become POSITIVELY charged ions
- There is a quick way to work out
what the charge on an ion should be
- The number of charges on an ion formed by a metal
is equal to the group number of the metal
- The number of charges on an ion formed by a non-metal
is equal to the group number minus eight
- The number of charges on an ion formed by a metal
is equal to the group number of the metal
- When metals react with non-metals, electrons are transferred
from the metal atoms to the non-metal atoms, forming ions
- Forming an ionic compound
- Forming an ionic compound
