The atomic number is equal to the number of protons in the atom. Therefore, if an element has an atomic number of 24 (which in this case is chromium) then it has 24 protons. The mass number is the sum of the number of protons and neutrons.
The atomic number of an atom is equivalent to the number of protons in its nucleus.
The number of protons is the atomic number.
The atomic number of an atom is determined by the number of protons it has.
The atomic number is determined by the number of protons in an atom. Therefore, if an atom has 65 protons, its atomic number is 65.
The number of protons in an atom is its atomic number.
The atomic number is equal to the number of protons in the nucleus and in a neutral atom will also equal the number of electrons.
The number of protons in an atom is equal to its atomic number.
The number of protons is identical to the number of electrons when an atom is in a neutral state.
16 The atomic number of an element is always the same as the number of protons in an atom of the element.
The atomic number is the number of protons in the atom. In the case of a neutral atom (as opposed to an ion), the atomic number is also equal to the total number of electrons.
It is based on number of protons. Consider an element has 20 protons.Its atomic number is twenty.
