The law of conservation states that matter can't be created or destroyed in a chemical reaction. When balancing an equation, both sides need to be equal. If both sides don't have the same amount of atoms for each element, it is unbalanced
Electrons have a negative charge
Ionic bond is a type of bond in which one or more atoms are transferred to another atom which results to two ions with opposite charge. They attract each other.
The atom of another element is removed and then gained by another element which produces a noble gas electron configuration.
Covalent bond is a type of bond in which a pair or more electrons are being shared by the atoms of two elements.
Because of this, the molecules become stable by sharing the electrons thus creating a noble gas configuration for each of the atom.
