Question

Arrange the isotopes of oxygen and carbon in order of decreasing number of neutrons.

Rank the isotopes from most o fewest neutrons. To rank items as equivalent, overlap them.

Answer 1

C-12 > C-13 > C-14,O-16 > C-16,O-18

Step-by-step explanation:

Generally, isotopes are described as atoms of the same elements with the same atomic number but different number of neutrons.

Hence,

For O-18, oxygen has an atomic number of 8 and neutron number of 10.

For C-14, carbon has an atomic number of 6 and neutron number of 8.

For C-13, carbon has an atomic number of 6 and neutron number of 7.

For C-16, carbon has an atomic number of 6 and neutron number of 10.

For carbon 12, carbon has an atomic number of 6 and neutron number of 6.

For O-16, oxygen has an atomic number of 8 and neutron number of 8.

Hence the rank from the fewest neutrons would be C-12>C-13>C-14,O-16>C-16,O-18
