Which argument best explains the charge of an atomic nucleus? (1 point)
An atomic nucleus is positively charged because it is composed of neutrons *
An atomic nucleus is positively charged because it is composed of protons.
An atomic nucleus is negatively charged because it is composed of electrons
An atomic nucleus is negatively charged because it is composed of
neutrons
What do an electron a neutron have in common?
Each particle has a mass of 1 amu *
Each particle exist inside and Atom
Each particle has an electrical charge
Each particle is located in the nucleus
Each particle has a mass of 1 amu
To answer the first question, the correct explanation for the charge of an atomic nucleus is:
- An atomic nucleus is positively charged because it is composed of protons.
Protons are positively charged particles, and they make up the majority of the mass of an atomic nucleus. Neutrons, on the other hand, have no charge, so they do not contribute to the overall charge of the nucleus.
As for the second question, the correct common characteristic between electrons and neutrons is:
- Each particle has a mass of 1 amu.
The atomic mass unit (amu) is a unit of mass commonly used to express the relative masses of atoms and subatomic particles. Both electrons and neutrons have a mass of approximately 1 amu. However, the key difference between them is that electrons have a negative electrical charge, while neutrons have no charge.
0 for 2
neutrons have no electrical charge (neutral)
