| What happens when metals and non-metals transfer electrons? | They become charged. These are called ions. |
| When is it called ionic bonding? | When there are bonded together by electrostatic attraction. |
| When does covalent bonding happen? | Non-metals can also share electrons between atoms. |
| When does metallic bonding occur? | Metals are bonded together as positive ions by electrons that move around |
| What are ionic bonding at room temperature? | Solids |
| Covalent bonding at room temperature? | Gases and liquids |
| Metallic bonding at room temperature? | Solids |
| Why do atoms form bonds? | To form a stable electronic structure, making them unreactive. Except for Helium. |
| What two groups have the electronic structure of a noble gas and a positive charge? | Group 1 and 2. |
| What two groups have the electronic structure of a noble gas and a negative charge? | Group 6 and 7. |
| What is electronic transfer during the formation of an ionic compound? | They can be represented by a dot and a cross diagram. |
| What is it called when two opposite charges attract each other? | They are called electrostatic attraction. |
| Why do they attract? | To form large packs of ions that form crystals. |
