Question

The element cxygen has atomic number 8 and mass number 16. Calculate the
number of protons, neutrons and electrons in it. Give the arrangement in energy
shells also.
​

Answer 1

Answer:

protons- 8

electrons- 8

neutrons-8

Answer 2

protons= 8

electrons=8

neutrons=8

Explanation:

we know that the mass number is neutrons+protons and the atomic number is basically the number of protons in an element. the number of protons and electrons in an atom is equal unless it is an ion of course.

so if we subtract the atomic number from the mass number, we get the neutron number.
