On a Periodic Table, each symbol has 2 numbers next to it. The top number is the mass number and the bottom number is the proton number.
The atomic number is equal to the number of protons.
The number of protons determine the atomic number of an element. There are the same amount of protons as electrons in a regular element.
The protons of an element determine the atomic number, also known as the proton number. Do not confuse this with mass number which is the number of protons and neutrons.
The number of protons determine the atomic number of an element. There are the same amount of protons as electrons in a regular element.
By the number of protons it has.
Electrons: 92neutrons: 143 protons: 92.
Number of protons or the atomic number of an atom determines what is the element.
The number of protons is the "atomic number", so you look that up in the periodic table.

The number of protons
Protons, neutrons and electrons
The number of protons determine what element it is, the number of neutrons determine what isotope it is.
