Question

calculate the number of electrons protons and neutrons present in an atom a (atomic number 17 and mass number 35)​

Answer 1

Answer:

number of electrons=17

number of proton=17

number of neutron=18

Explanation:

Atomic number=number of protons(which is equal to number of electrons)

so, number of protons=17

number of electrons=17

mass no.=no. of protons+ no. of neutrons

35= 17+no. of neutrons

therefore,

no. of neutrons= 35-17

= 18
