[ircasodle]

Symbol: Al
Atomic Number (Z): 13
Atomic mass: 26.98159 amu
Number of Protons/Electrons: 13
Number of Neutrons: 14
Period: 3
Block: p-block
Electrons per shell: 2,8,3
When the pure metal is obtained it is soft but it becomes hard when alloyed.
It is ductile in nature and can be beaten into very thin sheets. It's a good conductor of heat and electricity because of the 3+ charge, meaning there are 3 declocalised electrons moving freely between each aluminium atom, which helps them to quickly pass the energy applied to it.
It's also a corrosive resistant metal.

The Symbol Of Aluminium is given as :


It is represented by capital letter ‘A’ and the small letter ‘l’ .
so by combining A and l symbol of aluminium becomes “Al” as shown above.
Its Atomic number is 13.
Its mass number is 26.982.
It is derived from the first two letters of the word ‘Aluminium’
