Week 6 Homework: Alkali Earth metal of the week


Magnesium

Born in England

Can be used as food additive(with calcium it can help developing bone)

When Magnesium is burning, NEVER use water to try to banish the fire


Magnesium is highly reactive with oxygen

So when you add water to Magnesium, it rapidly and strongly steels oxygen from water, causing it burning stronger
