Which of the following is true in regard to a proton?Choose one or more:A. A proton has a 1+ charge. B. A neutral atom must have an equal number of protons and neutrons. C. A proton has a mass of about 1.0 amu. D. A proton has a 1- charge. E. The number of protons determines the identity of an element.

1. A PROTON HAS A +1 CHARGE

2. A PROTON HAS A MASS OF ABOUT 1.0 amu

3. THE NUMBER OF PROTONS DETERMINES THE IDENTITY OF AN ELEMENT

Explanation:

The proton is one of the three particles that make up the atom. Proton is a positively charge particle with a +1 charge. It neutralizes the negative charge of the electrons outside of the nucleus of the atom as the proton are located inside the nucleus of the atom. Proton has a mass of 1.0 amu which is about 1.67 * 10^-27 kg. The addition of the proton and the neutrons gives the molar mass of the atom.

Also, the identity of the cell that is the atomic number which gives the position of the element in the periodic table and also shows the individual characteristics of the atoms is determined by the number of protons in the nucleus of the atoms.

All the above options are true in regard to a proton.
