Question

Calculate the no of Protons, Electrons and
neutrons in oxygen with

mass 15
atomic no 8 with 2 unit negative charge:
​

Answer 1

Answer:

GIVEN THAT,

⇒Mass =15

⇒Atomic No=8

⇒Charge=2u.

No of PROTONS=8

NEUTRON=mass-atomic no

=15-8=7

ELECTRON=atomic no-charge

=8-2=6

SO,OXYGEN HAS:

PROTON:8

NEUTRON:7

ELECTRON:6
