17) For the following molecules, list the number and type (metal, nonmetal, or metalloid) of atoms that each contain. a. CO2 b. H2S C. NO2 d. SiO2 14. Provide the number of protons, neutrons, and electrons for an atom copper with a mass number of 64.

Expert Solution

Both carbon and oxygen are nonmetal. In a CO₂ molecule, there is 1 atom of carbon and 2 atoms of oxygen.
Hydrogen is a gas thus nonmetal while sulfur is nonmetal. In a H₂S molecule, there are two atoms of hydrogen and 1 atom of sulfur.
Both nitrogen and oxygen are nonmetal. In a NO₂ molecule, there is 1 atom of nitrogen and 2 atoms of oxygen.
Silicon is metalloid while oxygen is nonmetal. In a SiO₂ molecule, there is 1 atom of silicon and 2 atoms of oxygen.
