Explain why the protons can never change for a particular element. What subatomic particles can change and what do they form?

Protons can never change for any particular element because they're in the nucleus and the force keeping them there is extremely strong and hard to overcome. Electrons, however, orbit the nucleus and they change all the time. When electrons either leave or join an atom they form ions.

Positive ions (cations) are when electrons leave, so the positive charge is greater than the negative charges, and negative ions (anions) are when electrons join so the negative charge is greater than the positive charge.

hope this helps!

the answer would be 32*f

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
