The atomic number.
The amount of protons in an atom is its atomic number
The total amount of protons and neutrons in an atom is its mass number.
In an atom of an element, the amount of protons in that atom equal the amount of electrons in the atom, but only if it is a neutral atom. That then eqals the atomic number of that element.
The bigger number (Atomic mass) is the amount of protons (=same amount of electrons unless specified) and nutrons in an atom. The smaller number (atomic number) is the amount of protons only
Yes
An atom's atomic number gives us its number of protons. Fluorine's atomic number is 9. Thus, it has 9 protons.
An atom's atomic number gives us its number of protons. Carbon's atomic number is 6. Thus, it has 6 protons.
No it can't. There has to an equal amount of electrons as protons! This atom can't exist.
If the atomic number of an atom is 6 it means that the atom has 6 protons, the mass number on the other hand is the total amount of protons and neutrons in the atom. ( Remember- the amount of protons equals the amount of electrons). So for example if you wanted to find out the amount of neutrons in an atom, you would subtract the atomic number from the atomic mass for the answer. (Whole-protons=neutrons)
An atom's atomic number gives its number of protons. Zirconium has an atomic number of 40. Therefore, it must have 40 protons.
Neutral
The atomic number of an atom gives the number of protons in its nucleus, which also determines its unique identity as an element. It also indirectly gives the number of electrons in a neutral atom, as the number of protons is balanced by the number of electrons in the atom.
