Key Stage 2
Meaning
Key Stage 3
Meaning
Lithium is a Group 1 element, on the Periodic Table, with an atomic number of 3.
About Lithium
Molecular Structure
- Lithium has the chemical symbol Li.
- Lithium atoms join together in large numbers to form a giant metal molecule.
Atomic Structure
- Lithium has 3 protons and 4 neutrons in its nucleus giving it an Atomic Number of 3 and an atomic mass of 7.
- An atom of Lithium has only 1 electron in its outer shell.
Properties
- Lithium is the least reactive Alkali Metal.
- Lithium is more reactive than Carbon on the reactivity series so it must be extracted from its ore using electrolysis.
- Lithium oxidises quickly in the presence of Oxygen so it must be stored in oil.
- Lithium reacts strongly with water to produce Hydrogen gas and Lithium Hydroxide.
- Lithium is a solid at room temperature.
Key Stage 4
Meaning
Lithium is a Group 1 element, on the Periodic Table, with 3 protons in the nucleus.
About Lithium
Molecular Structure
- Lithium has the chemical symbol Li.
- Lithium atoms join together in a giant metallic structure.
Atomic Structure
- The most stable isotope of Lithium has 4 neutrons in its nucleus giving it an atomic mass of 7.
- An atom of Lithium has only 1 electron in its outer shell.
- Lithium ions have lost an electron to become positively charged.
