Sand, which is used in making glass, is formed mainly of the compound silica (a compound formed between silicon Si and oxygen O). Silicon is used also in computer chips. When mixed with steel, it makes the alloys harder and resistant to corrosion while oxygen is used in chemical industry and medical treatment. The documents below show some information about silicon and oxygen atoms. nb of protons nb of neutrons Nuclear charge Silicon atom 14 15 Oxygen atom 8+ Document 1 Document 2 1-Referring to document 1: 1.1- Indicate the number of electrons of silicon atom. 1.2- Determine the atomic number of silicon atom. 1.3- Calculate its mass number. 1.4- Write the atomic representation of silicon atom (Si).
