The number at the top of an element square is referred to as an atomic number. This number provides you with multiple information such as the number of protons and electrons the element has, and with the atomic number it is easier to locate the element on the periodic table. In this case, Carbon's atomic number would be 6, as well as how many protons and electrons are in its nucleus.
Carbon has 6 electrons. You can tell because its atomic number is 6, and atomic number is the number of protons. In a neutral atom, the numbers of protons and electrons are equal.
Symbol Name Atomic Number Atomic Mass
You can tell isotopes apart by the difference in there atomic mass numbers. Take for example the isotope Carbon-12. Carbon is the element name and 12 is the Atomic Mass of the element. The atomic mass number can (most?) always be changed, but the the atomic number ( the number above the Element symbol on the Periodic Table) cannot. Remember: The number of protons add by the number of neutrons equals the atomic mass number. The proton number = the atomic number, as of the number of electrons= the atomic number; hence the atomic number= number of proton = number of electron.
It is the same number as the atomic number example: Carbon Atomic number - 6 Mass - 12.01 So the number of protons is 6.
How many protons/ electrons that element has and where it is on the periodic table.

We use atomic number for recognize chemical elements. atomic number means, how many protons are there in a single atom.
Atomic number = Number of protons
Atomic number = Number of protons
Atomic number = Number of protons
Atomic number = Number of protons
