Key Stage 2
Meaning
Key Stage 3
Meaning
Strontium is a Group 2 element, on the Periodic Table, with an atomic number of 38.
About Strontium
- Strontium has the chemical formula Sr.
- Strontium as 38 protons and 50 neutrons in its nucleus giving it an Atomic Number of 38 and an atomic mass of 88.
- Strontium is a more reactive alkali earth metal than Calcium but less reactive than Barium.
- Strontium is more reactive than Carbon on the reactivity series so it must be extracted from its ore using electrolysis.
- Strontium reacts strongly with steam to produce Hydrogen gas and Strontium Hydroxide and strongly with acid to produce Strontium salts.
- Strontium is a solid at room temperature.
- An atom of Strontium has only 2 electrons in its outer shell.
- Strontium ions have lost 2 electrons to become positively charged.
Key Stage 4
