A chemical element is a material that can be used in chemistry .That means, it is any material, but it must be in its pure and natural state, meaning, fleece is not an element because it is usually wool, plastic, and polyester mixed together, and to mix them together, they were probably burned down and softened and had other things done to them. And water is not an element because it is Hydrogen and Oxygen mixed together(H2O). For example, natural, pure gold is an element. If you want to know all of the elements, look up a picture of the Periodic Table of elements. It will have the element's abbreviation, The full name usually, and its mass and chemical makeup and other things. There are 117 chemical elements, I am pretty sure.

No such element as 'silicicon'. If you mean 'silicon' , then its chemical symbol is 'Si'.
Fluorine is a natural chemical element.

The symbol on the periodic table means the abrevitation of the chemical element. For example, the chemical element symbol Pm stands for Promethium.
