What is chemical bonding? |
The force of attraction which keeps particles together in a substance |
|
|
What are the 3 types of bonds? |
1. Ionic bond 2. Covalent bond 3. Metallic bond |
|
|
Why are noble gases unreactive? |
They have a completely filled outer shell |
|
|
What does an element do to gain the noble gas stability? |
It needs to lose or gain electrons to completely fil its valence shell It uses the easiest way possible to gain it |
|
|
What are ions? |
Ions are charged particles |
|
|
What are cations? |
-Positively charged ions -Most likely to be metals as metals usually have less electrons in their valence shell than non-metals -Forms when an atom loses electrons |
|
|
What are anions? |
-Negatively charged ions -Most likely to be non-metals as they have a nearly filled outer shell -Formed when an atom gains electrons |
|
|
What is an ionic bond? |
-An ionic bond is the electrostatic force of attraction which exists between positive and negative ions -Usually formed between a metal and a non-metal |
|
|
What happens during the formation of an ionic bond? |
The metal loses electrons while the non-metal gains them. |
