Ionic bonding

?
How are ionic bonds formed?
Generally, metal atoms lose electrons to create a full shell and non-metals gain electrons to create a full shell.

What is an ion?
An ion is an atom with a positive or negative charge depending on the amount of electrons.
2 of 7
How do you calculate the numbers of protons, neutrons and electrons in simple ions when the atomic number and mass number?
In an atom number of protons = the number of electrons, but in an ion, there could be more or less electrons. Use this information to work it out.
3 of 7
Explain the formation of ions an ionic compounds from their atoms, limited to compounds of elements in groups 1, 2, 6 and 7.
Ions produced by metals in Groups 1 and 2 and by non-metals in Groups 6 and 7 have the electronic structure of a noble gas (Group 0).
4 of 7
Explain the use of the ending –ide.
It usually contains only two elements.
5 of 7
Explain the use of the ending -ate.
It contains three or more elements one of which is always oxygen.
6 of 7
Explain the structure of an ionic compound as a lattice structure.
A giant structure of ions = ionic compound. Held together by strong electrostatic forces of attraction between oppositely charged ions. The forces act in all directions in the lattice.
