5. What is the charge of an electron?
6. Where are the electrons located?
Answers & Comments
Answer:
1.There are three subatomic particles: protons, neutrons and electrons.
2.The two subatomic particles located in the nucleus of an atom are protons and neutrons.
3.Charge of proton is +1.
4.Neutrons are electrically neutral species. So, the charge on them is Zero.
5.Electron is considered as a negative charged particle and its amount is 1.60217662 × 10^-19 coulombs, absolutely opposite of proton.
6.Outside the nucleus, unlike protons and neutrons, which are located inside the nucleus at the center of the atom, electrons are found outside the nucleus. Because opposite electric charges attract each other, negative electrons are attracted to the positive nucleus.
