Chemistry: Bonding
| Question | Answer |
|---|---|
| What is a covelent bond | where atoms achieve a stable electron arrangement by sharing electrons |
| what are the 2 types of structure that covelent substances can form | molecular and network |
| how are atoms held together in a covelent bond | the equal attraction between 2 positive nuclei and the shared pair of electrons |
| what are the shapes for a covelent moleculars | linear bent angular tetrahedral |
| what are the elements that from a covelnt network | silicon |
| why do metals conduct | because they have delocalised electrons |
| what is an insulator | a material or substance that does not allow electricity to pass through it |
| what is electrolysis | process by which electricity is passed through an ionic compound to break it down into its elements |
| what power do you ise during electrolysis | DC to indentify the products |
| what is the valency number | size of chare |
| what is a molecule | a group of atoms held together by a covenltn bond |
| what is a discrete v=covelnt molecular | break froces of attraction between molecules but storea wide ragne of M>P and B>Pbut lower than covelent |
