Answer:
C. Solid
Explanation:
It's most about the kinetic energy, when molecules have the least amount of room to move around, they have the least amount of energy.
For example if you think about gas and how spread out the molecules are in order to evaporate, there it the highest amount of energy there.
First, let's find the number of neutrons in Calcium-40. to find the number of neutrons, you need to take the atomic mass minus atomic number
neutrons in Calcium---> 40 - 20 (atomic number) = 20 neutrons
potassium-40---> 40- 19= 21
scandium-44----> 44- 21= 23
argon-38---------> 38- 18= 20
chlorine-36------> 36- 17= 19
the answer is argon-38
