Which of the following statements about subatomic particles best characterizes electrons?
A. Positive charge, light, circling the nucleus
B. No charge, heavy, found in nucleus
C. Negative charge, light, circling the nucleus
D. Negative charge, heavy, circling the nucleus
Answer (3)
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.
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.
Electrons are negatively charged, light particles that orbit the nucleus of an atom. Their small mass, approximately 9.11 × 10^{-31} kg, makes them significantly lighter than protons and neutrons. Therefore, the best characterization from the given options is option C: Negative charge, light, circling the nucleus.
