Boron

Key Stage 2

Meaning

Boron is a solid.

Key Stage 3

A 2 dimensional representation of a Boron atom with 5 protons and 6 neutrons in the nucleus and 5 electrons orbiting the nucleus.

Meaning

Boron is a Group 3 metalloid element, on the Periodic Table, with an atomic number of 5.

About Boron

Boron has the chemical symbol B.

Atomic Structure

Boron as 5 protons and 6 neutrons in its nucleus giving it an Atomic Number of 5 and an atomic mass of 11.
Boron is in Period 2 of the Periodic Table because it has 2 electron shells.

Properties

Boron is a shiny solid at room temperature.

Key Stage 4

A 2 dimensional representation of the Bohr Model of a Boron-11 isotope with 5 protons and 6 neutrons in the nucleus and 2 electrons in the first shell and 3 in the outer shell.

Meaning

Boron is a Group 3 metalloid element, on the Periodic Table, with 5 protons in the nucleus.

About Boron

Boron has the chemical symbol B.

Atomic Structure

The most stable isotope of Boron has 6 neutrons in its nucleus giving it an atomic mass of 11.
Boron is in Period 2 of the Periodic Table because it has 2 electron shells.
Boron loses electrons to form positive metal ions.

Properties

Boron is a metalloid element so in some conditions it is an electrical conductor.
Boron is a shiny solid at standard temperature and pressure and has a high melting point.
