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.
Yes
In an atom, the number of protons is the same number as the atomic number.
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)
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
No - in fact it is quite rare
the amount of protons in an atom
Its atomic number. It tells you the number of protons it has. Each atom has its own unique amount of protons. The protons identify the element.
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 atomic number.
The atomic number of beryllium is 4. The atomic number of an atom says how many protons are in that atom. In an unionized atom, the protons and electrons are the same amount. Beryllium (unionized) has 4 electrons and 4 protons.
