Key Stage 3
Meaning
Magnesium is a Group 2 element, on the Periodic Table, with an atomic number of 12.
About Magnesium
- Magnesium has the chemical formula Mg.
- Magnesium as 12 protons and 12 neutrons in its nucleus giving it an Atomic Number of 12 and an atomic mass of 24.
- Magnesium is the least reactive alkali earth metal.
- Magnesium is more reactive than Carbon on the reactivity series so it must be extracted from its ore using electrolysis.
- Magnesium reacts strongly with steam to produce Hydrogen gas and Magnesium Hydroxide.
- Magnesium is a solid at room temperature.
- An atom of Magnesium has only 2 electrons in its outer shell.
- Magnesium ions have lost 2 electrons to become positively charged.
