Explain the relationship between atomic mass and atomic number?

Answer 1

mass is an infinite #

Answer 2

Atomic No. = number of protons in the nucleus

Atomic Mass = average of the number of protons and neutrons in a neutral atom + isotopes

Answer 3

Atomic number: number of protons in the nucleus which equals the number of electrons in the neutral atom.

Something called "mass number": number of protons in the nucleus plus number of neutrons.

Exact atomic mass of any particular isotope: very close to the mass number, but not quite, because of the energy released in forming the nucleus, and E = mc^2

Atomic mass of an element: if the element has more than one isotope, this is the weighted average of the different isotope masses.

Example, chlorine, atomic number 17, 2 isotopes with mass numbers 35 and 37and isotope masses very close to those numbers, around 75% 35Cl, average atomic mass around 35.5.

Answer 4

As a high-schooler, this is what they taught me:
Atomic number = the number of protons in nucleus
Atomic mass = Atomic number + the number of neutrons

Answer 5

atomic no.=no of protons =no. of electrons=say Z
atomic mass,M=no of neutrons(N)+no of protons(Z)
that is M=N+Z
where M-Atomic mass
N- no. of neutrons
Z-atomic no.
