Atomic number = number of protons # protons = # electrons IN NEUTRAL ATOMS. Today in Physical Science Chemistry: Inside the Atom Chapter 3 Part 2. How Atoms Differ Atoms differ in the number of protons they have. – Oxygen has 8 Protons, Fluorine 9 Protons, First 20 Elements in the...
2\. Above the symbol is the atomic number (Z) which is equal to the number of protons in the nucleus and the number of electrons in the electron cloud (given that the atom is neutral). For carbon Z=6. 3\. Below the symbol is the atomic mass. While this number is a weighted aver...

Protons and neutrons make up the nucleus and electrons orbit them in a cloud.Answer and Explanation: The mass number is not the number of protons. The mass number is the number of protons added to the number of neutrons. The mass number can be found......
