The same as the atomic number of platinum, 78.
Electrons, Neutrons, and Protrons
protrons, neutrons, and something else
The number of Protrons in an Atom.
Pt-Platinum Atomic number=78
Protons and neutrons are subatomic particles found in the nucleus of atoms (with the exception of hydrogen atoms, which have no neutrons).
The number of Protrons in an Atom.
atomic number
Atomic number
The number of protons in an atom is its atomic number.
yes
Electrons yes because atoms normaly consist of protrons, electrons and neutrons, so the answer is Yes they do. (everything has atoms)
Element with 12 protrons is magnesium, as the number of protons determines the element's identity on the periodic table.
