Verified answer

A1 = False - they are part of the nucleus

1 = false = they are NEUTrally charged..... No charge

2 = true

3 = True

4 = False - the number of electrons determines the valence

5 = C the electrons have negligible mass

Hi!

I did a little research and found the answers to your questions. I would, however, go over them because it's always good to double check answers.

1. A. - False - The nucleus contains protons

1. - Neutrons have a negative electrical charge. - False

2. - Electrons have almost no mass. - True

3. - Electrons are located only in specific shells around the atom. - True

4. - The valence of an atom is determined by the nucleus. - False

5. - The atomic mass of an atom equals the sum of the masses of the: - C - protons and neutrons

A. protons and electrons

B. electrons and neutrons

C. protons and neutrons

D. none of the above

You say that the person who answers your questions is not doing your homework. Yet, you asked this under Homework Help. Also, it seems to be written out as homework questions. Given the way you wrote your first and last "sentences" and your spelling, and the way the questions are worded and the tone of the questions, it truly does seem to be homework.

Here is some help: Try the library. Try your textbook. Try an Internet search engine.
