An ion is an atom which has more or less electrons than protons
All atoms want to have a full shell/empty outer shell
Noble gasses have already a full outer shell
All other elements will give or take electrons=chemical reaction
Covalent bonds are.Stronger than ionic
they make molecules and they are formed between non_metals
These bonds are between atoms fighting ever some electrons bonds where electrons are shared
Different forms of carbon: Carbon(black, it can burn)
Graphite(Grey, used as lubricant)
Diamond(Transparent, cutting hard material)
Differences between covalent and ionic compounds:
Ionic: Volatility: none
Solubility: most are very soluble
Electrical conductivity: only when dissolved in water
-liquid form
Covalent:Volatility:high
Solubility: some more, others not
Electrical conductivity:None
