| Question | Answer |
| ammonium ion | NH4+ |
| silver ion | Ag+ |
| lead (II) ion | Pb2+ |
| zinc ion | Zn2+ |
| hydroxide | OH- |
| nitrate | NO3- |
| carbonate | CO3 2- |
| sulfate | SO4 2- |
| phosphate | PO4 3- |
| Ionic compounds | have high melting and boiling points |
| why? (the reason why ic are solids at room temp) | Large amount of energy is required to overcome the strong electrostatic forces of attraction between oppositely charged ions in a giant ionic lattice structure |
| give an example lol | Refractories:- R are heat resistant materials with very high melting points. An example f an ionic refractory is magnesium oxide, MgO. It has a very high melting point if 2,800 C and is used to line the insides of high temperature furnaces. |
| ionic compounds also...? | do not conduct electricity in the solid state, but conduct when molten or in and aqueous state |
| wae???? | lol in a solid state , ions r held in a fixed position by string electrostatic forces of attraction and r immobile looool when melted or dissolved in water, the giant ionic lattice structure is broken down and these ions are mobile/able 2 move to conduct electricity. |
| rules for a substance to conduct electricity | there must be charge-carriers (aka electrons, cations, anions) the charge-carriers must be mobile |
| explain to thor how to draw a covalent bond (gd luck) | wow |
| lol now teach loki how to ionic bond | now the brothers can confuse each other lol |
| rules for covalent compound naming | dont change to 'ide' or add 'mono' for the first element if group 7 (hydrogen+halogen) no need tp put mono lol |
| simple molecular compounds.. | have simple molecular structure atoms r held tgt by strong covalent bonds btween molecules r only weak intermolecular forces of attraction lol |
| simple molecular compunds have? | low melting and boiling points |
| iM asKiNg yOu wAAAAe | little heat energy is required to overcome the weak intermolecular forces of attraction between the molecules |
| simple molecular compounds also | do not conduct electricity in any physical states |
| nan molla tho | there are no mobile ions or mobile electrons to act as charge carriers to conduct electricity. man im so sick of this fake love |
| oh wow | you made it |
