How many core and valence electrons does silicon have?
It has two electrons in its first shell, eight electrons in the second shell, and four electrons in the third shell. Since the electrons in the third shell are the outermost electrons, silicon has four valence electrons.
How is silicon like a metal?
A semi-metal (or metalloid), silicon possesses some properties of both metals and non-metals. Like water – but unlike most metals – silicon contracts in its liquid state and expands as it solidifies. It has relatively high melting and boiling points, and when crystallized forms a diamond cubic crystal structure.
