Chemical bonds
| Question | Answer |
|---|---|
| What makes up ionic bonds | Metal and non metal |
| What makes up covalent bonds | Only nonmetals |
| What makes up metallic bonds | Only metals |
| Are electrons being given and taken,or just given away in ionic bonds? | Given and take (transferred) |
| Are electrons being given and taken,or just given away in covalent bonds | Sharing |
| Are electrons being given and taken,or just given away in metallic bonds | Just given away |
| What melting and boiling points do ionic bonds have? | High melting and boiling point |
| What melting and boiling points do covalent bonds have? | Low melting point and boiling point |
| What melting and boiling points do metallic bonds have? | Moderately high melting point and high boiling point |
| Other properties of ionic bonds? | Brittle,dissolve in water,conduct electricity only when dissolved in water or liquid form |
| Other properties of covalent bonds? | Mostly gass at room temperature,soft,good insulators,do not dissolve in water |
| Other properties of metallic bond? | Lustrous(shiny), ductile,‘allowable(hammered into sheets), conduct electricity and heat |
| Why metals conduct electricity,shiny appearance,malleable,and ductile? Why don’t nonmetals conduct electricity? | Non metals do NOT have free flowing electrons.Metals do have free flowing electrons which allows light to reflect and heat to go through electrons. |
