Atomic number is the number of protons in the nucleus of an atom while the mass number is the sum of the protons and neutrons in the nucleus of an atom. for example lithium has an atomic number of 3 and a mass number of 7. Therefore lithium has 3 protons and 4 neutrons.
Atomic number 27 : Cobalt Atomic number 28 : Nickel Atomic number 29 : Copper Atomic number 30 : Zinc Atomic number 31 : Gallium
11...There are 11 electrons in Na1+ the only difference between Na1+ and Na is Na1+ has 1 more proton...there is no difference in electrons. Hope this helps :)
You get the number of neutrons in the atom. The mass number represents the total number of protons and neutrons in the nucleus, while the atomic number represents the number of protons. Subtracting the atomic number from the mass number gives you the number of neutrons because the difference accounts for the protons.
The atomic number and number of protons are always the same in a normal element.
Chemists can state this with certainty because the periodic table follows a specific pattern in terms of atomic number and electron configuration. All elements have been discovered up to atomic number 118, and there are no gaps between sulfur (atomic number 16) and chlorine (atomic number 17) in the periodic table, indicating that no elements are missing between them. This knowledge of the periodic table's structure allows chemists to confidently assert that no new element will be found in this region.
It is equal to the difference between atomic number and Atomic Mass number. A+
the difference between the atomic number and the average weight
Atomic mass represents the total mass of an atom, combining the mass of protons, neutrons, and electrons. Atomic number, on the other hand, is the number of protons in the nucleus of an atom, which determines its chemical properties and element identity.
Atomic number is the amount of electrons. Atomic mass is the amount of protons and neutrons.

Neptunium has the atomic number 93 and americium has the atomic number 95.
Calcium-40: The atomic number of calcium is 20 and the number of neutrons is always the difference between the atomic mass and the atomic number.

Atomic mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
The atomic number is the number of protons in the atom.
