Question

Which of the following statements about subatomic particles best characterizes electrons? A positive charge, light, circling the nucleusB no charge, heavy, found in nucleusC negative charge, light, circling the nucleus D negative charge, heavy, circling the nucleus

Answer 1

The answer should be (C) negative charge, light and circling the nucleus.

Why? ---- An electron always has negative charge. Its mass is 1/ 1900 times the mass of proton and it circles the nucleus.

Answer 2

Every electron carries one elementary negative charge. Concerning mass,
it takes roughly 1,840 electrons to make enough mass for 1 proton or 1 neutron.
Electrons don't necessarily have to stay connected to an atom, but when they do,
they circle the nucleus.

So you should select (C): ==> Negative, ==> light, ==> circling the nucleus.
