Elements have only one type of atom in their structure.
These atoms can react with one another.
Compound - A substance where the atoms of two or more elements are chemically combined.
Chemical bond - Transferring or sharing electrons in outermost shell.
Ionic bond is where a metal and non-metal combine.
When the electron is lost from the metal to the non-metal. They both become Ions!
If an electron is lost, it becomes positively charged amd if ones gained, it becomes negatively charged.
