Answer:
Electrons, with a charge of -1.
Explanation:
The nucleus of the atom is composed of protons and neutrons.
The nucleus is where the bulk of the mass of an atom is found.
Electrons orbit the nucleus in various energy levels.
Protons have a charge of +1, neutrons have no charge, and electrons have a charge of -1.

Answer:
The correct answer is B. and C. according to me!
<span>C. Static electricity. Except that electrons are never really at rest.</span>
<span>The answer to this question would be: 14g of Carbon
In this question, you are given the weight of the element. Then, to find the number of atoms you need to divide the weight with the molecular mass of the each element.
14 g c /(12 g/mole)= 1.167 mole
102 g ag </span>/(107 g/mole)= 0.95 mole<span>
49 g cr </span>/(52 g/mole)= 0.94 mole<span>
202 g pb </span>/(207 g/mole)= 0.975 mole
