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
The atomic number and number of protons are always the same in a normal element.
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 :)
Every elements has atomic number, elements identity determined the number of protons in its nucleus.
Number of neutrons = Atomic mass of an isotope - Atomic number of an element The atomic number of darmstadtium is 110; darmstadtium isotopes has massess between 267 and 281.
It is equal to the difference between atomic number and Atomic Mass number. A+
the difference between the atomic number and the average weight
Yes
Atomic number is the amount of electrons. Atomic mass is the amount of protons and neutrons.
The atomic number represents the number of protons in an atom's nucleus, determining its chemical properties and element identity. Atomic mass is the total mass of an atom, which includes the sum of its protons, neutrons, and electrons.

Neptunium has the atomic number 93 and americium has the atomic number 95.
atomic number = number of protons mass number = number of protons + number of neutrons
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 refers to the total mass of an atom, including the mass of protons, neutrons, and electrons. Atomic number, on the other hand, represents the number of protons in the nucleus of an atom, which determines its chemical properties and place on the periodic table.
it's equal to the difference between atomic number and atomic mass number
