Why isn't glass on the periodic table?

Answer 1

Plastic is a compound, not an element. It is made mainly from carbon, hydrogen, and oxygen, all of which are elements found on the Periodic Table of Elements.

Answer 2

The periodic table is a table of chemical elements, an element being a pure substance containing only one kind of atom.

'Glass' is a name that can apply to several compounds, all which are non-crystalline solids. For example, the glass used in a window is mostly silicon dioxide, with Sodium Oxide and Calcium Oxide. Compounds do not belong on the periodic table.

Answer 3

Glass is not on the periodic table because it is not an element. Glass is a non-crystalline solid typically made from silicon dioxide and other compounds, which do appear on the periodic table as elements. The composition of glass can vary depending on its intended use, so it's not a singular element to be included on the periodic table.

Answer 4

You can not find plastic on the Periodic Table as it is not an element. An element is made up of all the same types of atoms, but plastic is made up of different atoms - it is a compound.
