The total of number of protons in the nucleas gives you the atomic number.
Atomic Number It is thre position of the atom in the periodic table. It is the number of protons in the neucleud. It is the number of electrons in the neutally charged atoms. Atomic MASS it the total of the protons and neutrons in the atom.
The number of protons in the nucleus of an element gives that element its ATOMIC NUMBER.
To find the number of neutrons in an atom, you would subtract the atomic number (number of protons) from the atomic mass (sum of protons and neutrons). The difference between the atomic mass and the atomic number gives you the number of neutrons in the atom.
The atomic number is determined by the number of protons, which are located in the nucleus.
The atomic number of F (fluorine) is 9 and the atomic number of Na (sodium) is 11. Adding them together gives 20, which is the atomic number of calcium (Ca).
Mass
The atomic number.
The number of protons gives the atomic number. The number of electrons are equal to the number protons unless the atom is ionized. The number of neutrons determines which isotope you have. Hope that helps
The atomic number denotes the number of protons in an atom where the mass number gives the sum of protons and neutrons.
An atomic number goes with a single element notto a combination of elements.
An element's atomic number gives its number of protons. Lutetium's atomic number is 71. Thus, it has 71 protons.
