Key Stage 3
Meaning
Beryllium is a Group 2 element , on the Periodic Table, with an atomic number of 4.
About Beryllium
- Beryllium has the chemical formula Be.
- Beryllium as 4 protons and 5 neutrons in its nucleus giving it an Atomic Number of 4 and an atomic mass of 9.
- Beryllium is the least reactive alkali earth metal.
- Beryllium is more reactive than Carbon on the reactivity series so it must be extracted from its ore using electrolysis.
- Beryllium reacts strongly with steam to produce Hydrogen gas and Beryllium Hydroxide.
- An atom of Beryllium has only 2 electrons in its outer shell.
- Beryllium ions have lost 2 electrons to become positively charged.
