Q

Atomic reactions

A

Atoms take part in in chemical reactions to achieve a full outer shell of electrons which is very stable like group 0. They can achieve this by either losing gaining or sharing elections from the outer shell. If an atom loses or gains electrons, the numbers of protons and electrons are no longer equal and a charged ion is formed. The charge on the iron depends on the number of electrons lost losing one electron results plus one ion.

Q

Forming compounds

A

When a metal and a nonmetal react to form a compound transferring of electrons from the metal atom to the non-metal atom occurs
An IONIC bond is formed, which is the electrostatic attraction between the positive cation and negetive anion (negetively charged ions).
Ionic compounds and neutral they have no charge. This is because the positive ion charge cancels out the negative ion charge. The ratio of cation to anion is very important to ensure the positive and negative charges cancel

Q

Ionic compound

A

The ions in a solid ionic compound are not randomly arranged. Instead, they have a regular, repeating arrangement called an ionic lattice. The lattice is formed because the ions attract each other and form a regular pattern with oppositely charged ions next to each other. The ionic lattice is held together by
ionic bonds. In three-dimensional models, ionic bonds are shown as straight lines between ions
