Key Stage 2

Meaning

Strontium is a metal.

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

Meaning

Strontium is a Group 2 element, on the Periodic Table, with 38 protons in the nucleus.

About Strontium

The most stable isotope of Strontium has 50 neutrons in its nucleus giving it 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 standard temperature and pressure.
An atom of Strontium has only 2 electrons in its outer shell.
Strontium ions have lost two electrons to become positively charged.
