The atomic number of oxygen is 8
The atomic number of zinc is 30
The atomic number of Lithium is 3
The atomic mass of oxygen is 15.999, for zinc it is 65.39, and Lithium is 6.941
The number of protons for oxygen is 8, for zinc it is 30, and for Lithium is 3.
The number of neutrons for oxygen is 8, for zinc it is 35, and for lithium is 4. To find the number of neutrons you have to do atomic mass - atomic number.I rounded the answers to find the #of neutrons.
The number of electrons is always the same as the number or protons so the answer is for oxygen 8, zinc 30, and lithium 3.
I hope this helped you. If you can please make branliest :)
