Ions

Ions

1. Atoms can gain or lose electrons when they react. They then become ions.

2. Metal atoms lose electrons to become positive ions.

   • They lose negatively charged electrons, with makes them positive overall.

3. Non-metal atoms gain electrons to become negative ions

   • They gain negatively charged electrons, which makes them negative overall.

4. Group 1 and 2 have gained a positive charge they lose electrons to gain a positive charge.

   • Mg ion= Mg2+ .Protons= 12 .Electrons= 10 (12-2) .Neutrons= 12 (24-12)

5. Group 3 and 5 have gained a negative charge they gained electrons to gain a negative charge.

   • Nitrogen ion= N3- .Protons=7 .Electrons= 10 (7+3) .Neutrons= 7 (14-7)
