Key Stage 2

Meaning

Beryllium is a metal.

Key Stage 3

The chemical symbol for Beryllium. A 2 dimensional representation of a Beryllium atom with 4 protons and 5 neutrons in the nucleus and 4 electrons orbiting the nucleus.

Meaning

Beryllium is a Group 2 element, on the Periodic Table, with an atomic number of 4.

About Beryllium

Molecular Structure

Beryllium has the chemical symbol Be. Beryllium atoms join together in large numbers to form a giant metal molecule.

Atomic Structure

Beryllium as 4 protons and 5 neutrons in its nucleus giving it an Atomic Number of 4 and an atomic mass of 9. An atom of Beryllium has only 2 electrons in its outer shell.

Properties

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 and reacts strongly with acids to produce a Beryllium salt. Lithium is a solid at room temperature.

Key Stage 4

The chemical symbol for Beryllium. A 2 dimensional representation of the Bohr Model of a Beryllium-9 isotope with 4 protons and 5 neutrons in the nucleus and 2 electrons in the first shell and 2 in the outer shell.

Meaning

Beryllium is a Group 2 element, on the Periodic Table, with 4 protons in the nucleus.

About Beryllium

Molecular Structure

Beryllium has the chemical symbol Be. Beryllium atoms join together in a giant metallic structure.

Atomic Structure

The most stable isotope of Beryllium has 5 neutrons in its nucleus giving it an atomic mass of 9. An atom of Beryllium has only 2 electrons in its outer shell. Beryllium ions have lost two electrons to become positively charged.

Properties

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 and reacts strongly with acids to produce a Beryllium salt. Beryllium is a solid at standard temperature and pressure.

Beryllium always has 4 protons. The most stable isotope has 5 neutrons.
