12 electrons, 12 protons, and 16 neutrons
Radon has 86 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a radon isotope = Mass number - 86
Copper has 29 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a copper isotope = Mass number - 29
Sodium has 11 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a sodium isotope = Mass number - 11
Yes, the muon is a subatomic elementary particle. The subatomic label is not really needed; all elementary particles are subatomic.
no, a molecule is composed of 2 or more atoms.
The isotope 12C has 6 protons, neutrons and electrons.
An atom contain protons, neutrons and electrons. The number of these particles is different for each isotope.
