Formation of ions

What are ions?

Charged particles

How to atoms try gain full outer shells?

Through losing or gaining electrons

What happens when metals form ions?

they lose electrons to form positive ions

What happens when a non-metals forms ions?

gain electrons to form negative ions

What is the charge of any ion?

The electrons it gained or lost

The elements in which groups are most likely to form ions?

1,2,6,7

How do you find an ions charged for an element?

Their group number is how many electrons they have in their outer shell, so they will all need to gain or lose the same number of electrons

Write the ions each group will form and a half equation for an element in each

Group 1: 1⁺ ions ( Na→ Na⁺ + e^- )

Group 2: 2⁺ ions ( Mg → Mg²⁺ + 2e^-)

Group 6: 2^- ions ( Cl + e^- → Cl^- )

Group 7: 1^- ions ( O + 2e^- → O^2- )
