The mass number of Fe2+ is 56. How many neutrons are there in a single Fe2+ atom? 28
30

false

because it does not have the potential to be entirely used up

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

level 4 to level 2 : ))

the answer is yes

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.
