Question

A proton has a ________ charge, is located _________, and has a relative mass of __________ amu.

1) positive charge, in the nucleus, 1
2) negative charge, in shells around the nucleus, 0
3) no charge, in the nucleus, 1
4) no charge, in shells around the nucleus, 0

Answer 1

A proton has a positive charge, is located in the nucleus, and has a relative mass of approximately 1 amu.

Step-by-step explanation:

A proton has a positive charge, is located in the nucleus, and has a relative mass of 1 atomic mass unit (amu). Protons, along with neutrons, make up the bulk of an atom's mass, and each has a mass of roughly 1 amu; however, protons possess a +1 charge while neutrons carry no charge. The mass of a proton is approximately 1.0073 amu. In contrast, electrons with a mass of about 0.00055 amu have a negative charge equal in magnitude to the proton's positive charge and orbit the nucleus in shells.
