The total number of protons and neutrons present in the atom of an element is known as its mass number. It is represented by A. Mass number (A)=Number of protons +Number of neutrons (n) `implies` mass of number (A)=Atomic number (Z)+ Number of neutrons (n) `implies A=Z+n` Number of neutrons in nucleus We know `A=Z+n implies n=A-Z` In an element A=Z identify the element

The number of protons and neutrons is always equal in an atom of an element .
Mass number = number of .............. + number of neutrons .
There are 14 protons and 13 neutrons in the nucleus of an atom. What is its mass number ?
The number of electrons and neutrons of an element is 18 and 20 respectively . Its mass number is
The atomic number of an element is 11 and its mass number is 23. The respective number of elec trons, protons and neutrons in this atom will be
Atomic number of a nucleus is Z and atomic mass is M . The number of neutron is.
There are 15 protons and 16 neutrons in the nucleus of an element. Calculate its atomic number and mass number. How will you represent the element?
