Atomic Number :-
atomic number of an element is the number of protons present in the nucleus of the atom. (since atoms are electrically neutral the number of protons in an atom is equal to the number of electrons in an atom)
Atomic Mass :-
atomic mass of an element is the number which tells us how many times an atom of that element is heavier than an atom of hydrogen (whose atomic weight is taken as unity [1])
the Atomic Mass
protons + electrons= atomic mass NUMBER, not the atomic mass.
mass number=atomic number+no. of neutrons
The different mass numbers are due to different numbers of neutrons.
the Atomic Mass
the atomic mass
Neon is a non meta element. Atomic mass of it is 20 Atomic number of it is1 180.
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
There are no symbols for atomic mass and number. They're just written as numbers.
Atomic mass is found by adding together the individual masses of the numbers of protons, neutrons, and electrons in the atom.--> Atomic Mass = protons + neutrons
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
Atomic mass and different numbers of neutrons.
