They would then be able to say, for example, that atoms with an atomic number of one (for which they have learnt to use the symbol H) join together in pairs to form H2 molecules, that atoms with a nuclear charge of 17 (symbol Cl) join together similarly to form Cl2 molecules, and ...

Each element has a chemical symbol that is the same in every language. Some are obvious, such as Li for Lithium, but some are harder to decipher. The first letter is always written as a capital, and the second is lowercase. Tungsten has the symbol W – this is because tungsten is wolf...
The number of hydrogen must match the oxidation number of the metal. For example, the symbol for calcium hydride is CaH2, but for Tin it’s SnH4. Uses for Metal Hydrides Metal hydrides are often used in fuel cell applications that use hydrogen as a fuel. Nickel hydrides are often found ...
