Yes but only if there are no neutrons, such as in hydrogen (atomic number=1, relative Atomic Mass-1)
The atomic mass of an element is equal to the number of protons.
No, the atomic mass number is the number of protons plus the number of neutrons. The atomic mass of an atom is the total mass in a motionless atom.
Atomic mass is the number of protons and neutrons in an atom.
false
It looks like you have combined two concepts. The number of protons in an atom is the atomic number. The sum of the protons and the neutrons in an atom is the mass number. There is no such thing as an atomic mass number.
The atomic mass of an element is equal to the number of protons.
No, the atomic mass number is the number of protons plus the number of neutrons. The atomic mass of an atom is the total mass in a motionless atom.
It is equal to the difference between atomic number and Atomic Mass number. A+
atomic mass is contributed mainly by protons and neutrons. it is the mass of an atom. atomic number on the other hand is contributed by protons and is equal to the number of protons in the atom
The atomic number is equal to either the number of electrons or the protons of a particular atom. The atomic mass in a.m.u. is equal to the sum of protons and neutrons in an atom.
The atomic number is the number of protons in an atom (which equal the number of electrons present) The atomic mass is the number of protons+neutrons in an atom
Atomic mass is the number of protons and neutrons in an atom.
number of protons = atomic mass
protons + electrons= atomic mass NUMBER, not the atomic mass.
yes
The mass number is a whole number that is equal to the sum of protons and neutrons in an atom. Mass number is represented by the letter (A) orA= Z + N (Z) represent the atomic number or the number of protons in the nucleus.
