Question

an alpha particle has a mass of 2 amu. a mass of 4 amu. a charge of -1. neither mass nor charge. question 8 6 pts a beta particle has a mass of 4 amu. a charge of +4. a charge of -1. neither mass nor charge.

Explanation:

An alpha particle is a helium nucleus (2 protons + 2 neutrons), so its mass is ~4 amu. A beta particle is an electron, which has a charge of -1.

Answer:

For the alpha particle question: a mass of 4 amu.
For Question 8 (beta particle): a charge of -1.
