When an atom loses one electron it forms an ion. The atom becomes charged. It has more positive charges in its nucleus than negative electrons surrounding it, so the charge is positive, it has made a positive ion.
The same happens when an atom gains an electron apart from the charge now becomes negative.
Each atom always wants to become stable.
The electron arrangement is 2,8,8,8... and so on.
So for example sodiums atomic proton number is 11 and is set out like 2,8,1.
It needs to loose 1 electron to become stable.
Its ion is represented as Na+

How are ionic substances held together?
Ionic substances are held together ionic bonds, which are the electrostatic attractions between oppositely charged ions.
What type of substances make up ionic bonds?
Usually, ionic bonds are formed between a metal and a non-metal.
Are there Substances without covalent bond?
Ionic and metallic substances both do not have covalent bonds!
What type of substances form ionic bonds?
The male genitalia
Waters ability to dissolve ionic substances?
Water can dissolve ionic substances because in both substances the bond are very polar. When a solute is added to water, some of water's hydrogen bonds break as the water forms intermolecular bonds with the solute. Because ionic substances are polar, the new intermolecular bonds formed when they dissolve in water are quite strong, and can compensate for the energy lost when breaking the water's hydrogen bonds.
Are things made of ionic bonds soft?
ionic substances tend to be crystalline and brittle- although they are often encounterd as fine powders so these physical characteristics are not apparent

A compound held together by ionic bonds is?
releases ions into the substances
Are ionic bonds important in Br2?
Bromine gas, Br2, has covalent bonds. However, the element bromine does form ionic bonds with other substances (sodium bromide, etc.).
Are substances with ionic or covalent bonds more likely to dissociate in water?
Ionic compounds dissociate when they dissolve in water.
Contrast ionioc and molecular substances in terms of the types of attractive forces that govern their behavior?
Ionic substances are held together by ionic bonds which are much stronger than the inter molecular bonds that hold together molecules.
What describes the units that make up substances formed by ionic bonding?
The term that describes the units that make up substances formed by ionic bonding is ions. This may also be referred to as ionic bonds.
Why is calcium sulfate not soluble in non polar substances?
Calcium sulfate has ionic bonds.
