2. 1 mass, 0 charge
3. Resistant but malleable, usually extracted from the ground, solids at room temperature except for mercury, react with acids to make salt and hydrogen, conduct heat and electricity, used for building bridges and buildings because they are a strong material, ductile, Sonorous and magnetic metals are Cobalt, Iron and nickel.
4. is used to make crates and ropes
5. Atoms bond in order to gain a full outer shell of electrons. When atoms form ions, by gaining or loosing electrons, we call this type of bonding Ionic.
