Which subatomic particles have approximately the same mass? protons and electrons

neutrons and electrons

protons and neutrons

electrons and atoms

The 3rd one is correct

Explanation:

Protons and neutrons have approximately the same mass, about 1.67 × 10−24 grams, which scientists define as one atomic mass unit (amu) or one Dalton. Each electron has a negative charge (−1) equal to the positive charge of a proton (+1). Neutrons are uncharged particles found within the nucleus.

Explanation:

protons and neutrons have approximately the same size, the electron is 1847th, (I think), the size of a proton
