- 1What are the types of bonds?Ionic bonds, covalent bonds and metallic bonds.
- 2Ionic bonding occurs when?Compounds from metals combined with non-metals
- 3In ionic bonding how are the particles?The particles are oppositely charged ions
- 4Covalent bonding occurs when?Compounds of non-metals combined with non-metals in most non-metallic elements.

- 9What happens when metals and non-metals transfer electrons?They become charged. These are called ions.
- 10When is it called ionic bonding?When there are bonded together by electrostatic attraction.
- 11When does covalent bonding happen?Non-metals can also share electrons between atoms.
- 12When does metallic bonding occur?Metals are bonded together as positive ions by electrons that move around
- 13What are ionic bonding at room temperature?Solids
- 14Covalent bonding at room temperature?Gases and liquids
- 15Metallic bonding at room temperature?Solids
- 16Why do atoms form bonds?To form a stable electronic structure, making them unreactive. Except for Helium.
- 17What two groups have the electronic structure of a noble gas and a positive charge?Group 1 and 2.
- 18What two groups have the electronic structure of a noble gas and a negative charge?Group 6 and 7.
- 19What is electronic transfer during the formation of an ionic compound?They can be represented by a dot and a cross diagram.
- 20What is it called when two opposite charges attract each other?They are called electrostatic attraction.
- 21Why do they attract?To form large packs of ions that form crystals.
