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
2 answers:
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.

Answer:
Speed = 8.34 m/s
Explanation:
Given =
Distance = 2 5 0 meters
Time = 3 0 seconds
Solution =
Speed = Distance / Time
Speed = 250/30
Speed = 8.3333333 m/s.
Speed = 8.34 m/s
