Neon has an atomic number of 10, hence the configuration of [Ne] 3s^2 3p^1 represents an element with an atomic number of 13. This element is Aluminium (Al). 

The electronic configuration of aluminium with 13 electrons can be written as:

`1s^2 2s^2 2p^6 3s^2 3p^1`

Aluminium is a metal and belongs to group IIIA of the periodic table. It is represented by the symbol Al and has 3 valence electrons. The cation of aluminium is [`Al^(3+)` ] and is attained by losing the valence electrons from the 3s and 3p orbitals. Aluminium is a good conductor of heat & electricity and is commonly used for manufacturing of electrical cable, kitchen accessories, etc. It is also the most abundant metal in the Earth's crust. 

Hope this helps.
