Question

Numner of electons protons and neutrons lresent in 17cl35 17cl 37

Answer 1

Answer:

The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

Answer 2

Answer:

Correct option is

B

no. of neutrons

                                 17Cl35  17Cl36  17Cl37

number of neutrons =  18        19        20

number of protons   =  17        17         17

number of electrons=  17       17        17
