Answer 1

B. 160 has 8 neutrons, whereas 180 has 10 neutrons.

Step-by-step explanation:

The proton of an element is also known as the atomic number. Oxygen has an atomic number of 8 and also a proton of 8. Neutron is however calculated by the subtraction of the mass number from the atomic number (proton).

This results in 160 having 8 neutrons because the mass number(16) is subtracted from the atomic number to give 8 neutrons, whereas 180 has 10 neutrons as a result of the mass number 18- the atomic number(8) to give 10.
