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 substance in which one or more atoms have the same number of protons is called an element. Each element is defined by its unique number of protons, known as the atomic number. For example, all carbon atoms have six protons, categorizing them as carbon. Elements can exist as single atoms or as molecules consisting of two or more atoms of the same or different elements.
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)
