New cards
Properties of alkali metals
Soft
Low density
Very reactive
2
New cards
Why do alkali metals lose their electrons so easily
There is only one electron in the outer shell meaning less energy is needed to break away the electron
3
New cards
Why does reactivity increase as we go down group 1
The size of the atom increases which means electrostatic force of attraction decreases between the nucleus and electron meaning less energy is needed to overcome the force

New cards
Alkali metal + water →
