| What are group 1 metals called | Alkali metals |
| Alkali metals during a chemical reaction | Since they have one electron in their outermost shell, its usally given away |
| Lithium | Least reactive of alkali metals |
| What happens when lithium is reacted with oxygen | It burns with a red flame
Lithium floats on the surface and there are bubbles of hydrogen gas |
| Sodium | More reactive than Lithium
burns with yellow/orange flame when reacted with oxygen |
| Why is sodium more reactive than Lithium | Its outer electron is less strongly attracted to the nucleus, which means it can lose an electron easier |
| Potassium | More reactive than lithium sodium because its outer electron is least strongly attracted to the nucleus |
| Potassium with oxygen | burns with a lilac flame when reacted with oxygen |
| Alkali metals with water | - The metal floats on surface
- melts to create a metal hydroxide |
| Alkali metals with chlorine | - metal chloride(salt) is produced
- Dissolves in water to give a colorless solution |
| Alkali metals with oxygen | Silvery shiny to dull metal oxide |
