No. Of protons= No. Of electrons= Atomic no.
So, no. Of protons in iron atom=26
And, no. Of neutrons= atomic no. - no. Of protons
So, no. Of neutrons in iron atom= 56-26=30 regards
The atomic number of an element is 11 and its mass number is 23. The correct order representing the number of electrons, protons and neutrons respectively in this atom is
An atom has 26 electrons and its atomic weight is 56. The number of neutrons in the nucleus of the atom will be
