Students are completing a table about a particular subatomic particle that make up an atom.

what best explains how they should complete the table?

mass / location / charge
1 / / has no charge

a. with “inside the nucleus,” because the particle is a proton
b. with “inside the nucleus,” because the particle is a neutron
c. with “outside the nucleus,” because the particle is a proton
d. with “outside the nucleus,” because the particle is an electron

option B.with “Inside the nucleus,” because the particle is a neutron.

Explanation:

You have to complete this table:

mass | location | charge

  1            ?          Has no charge

The atom is constituted by 3 subatomic particles, namely electron, proton, and neutron.

Since the gold foil experiment performed by Geiger and Marsden (1909), who collaborated with Ernest Rutherford, it  was stablished that the atom contains a dense positively charged nucleus, which has almost all the mass of the atom.

The positive charge comes from the subatomic particle named proton.

A few time later, a second subatomic particle inside the nucleus, was discovered. This particle has not charge and has almost the same mass than the proton. Because the absence of charge it was named neutron.

Hence, the relative masses of the protons and neutrons are 1 / 1. As said, both are in the nucleus, and while the proton has positive charge, the neutron has no charge. So, the table is completed with inside the nucleus, because the particle is a neutron:

mass    |     location                        |    charge

  1              inside the nucleus         Has no charge

answer; i believe that the correct answer is (a) potassium(k)
