- Discussion - Together, the number of protons and the number of neutrons determine an elements mass number mass number = protons + neutrons. Lead atoms bond together and they make up the lead that we use as a pencil. Oxygen, O. Oxygen is in Group 6. It has six electrons in its outer shell. It gains two electrons from one or two other atoms in reactions, forming an oxide ion, O 2-.
- Conclusion -
The atomic number is 6 and the mass number is 12 .
The Number of protons is 6, number of electrons is 6 and 6 Neutrons.
The first shell have 2 electrons and the second shell have 4 electrons we can lost the sound shell and will have 4+.
