Where are the proton neutron and electron located and what charge do they have?

Answer 1

AtomsThe charge on a proton is +1. Its location is the nucleus, and its mass is 1.67262 x 10-27 kg. Protons have an effective size of about 1.2 x 10-15 m, and the nucleus is roughly the cube root of the number of nucleons (protons and neutrons) times that typical proton size, usually still on the order of 10-15 to 10-14 m in size.

The charge on an electron is -1. It is found in a region around the nucleus called the electron cloud. The mass of an electron is 9.10939 x 10-31 kg (1836 times lighter than the mass of a proton). The typical size of the electron cloud is usually 5 x 10-11 to 10-10 m in size, about 100,000 times larger than the nucleus.

The charge of a neutron is 0, and it is located in the nucleus along with the proton(s). The mass of the neutron is 1.67493 x 10-27 kg.

The elementary charge is equal to 1.60218 x 10-19 Coulombs. The proton and electron each carry this charge, but the sign of the charge will be positive for the proton, and negative for the electron.

Note: The mass of the proton and the mass of the neutron apply to the individual particles. When protons and neutrons are combined (fused) in a nucleus to make an atom, they all give up a bit of their mass (mass deficit) to create binding energy (or nuclear glue). This is necessary to offset the repulsion of the protons (which are like charges, and like charges repel), and it is absolutely necessary for this to happen to make the nucleus stick together.

Answer 2

Positively charged protons and neutral neutrons are located within the nucleus. Negatively charged electrons are located outside the nucleus.

Answer 3

The proton charge is 1+ the neutron is 0 the electron is 1-

Answer 4

Protons and neutrons are in nucleus. Neutrons doe not contain any charge.
