True or false

choose the correct answer

Answer 1

Here are the answers to each of the statements:

1. Electrons are negative. True
2. Electrons are found in the nucleus. False
3. Protons and electrons have the same mass. False
4. Most of the mass of an atom is in the electron cloud. False
5. Neutrons are negatively charged. False
6. The electron is the smallest of the three subatomic particles. True
7. The center of the atom is the nucleus. True
8. Protons and neutrons are found in the nucleus. True
9. Neutrons have no charge. True
10. Protons have a positive charge. True
11. The nucleus takes up most of the space in an atom. False
12. Neutrons and protons have the same mass. True (they have very similar masses, but neutrons are slightly more massive)

So the complete set of answers is:

1. True
2. False
3. False
4. False
5. False
6. True
7. True
8. True
