What best explains how they should complete the table?
with "inside the nucleus," because the particle is a proton
with "inside the nucleus," because the particle is a neutron
with "outside the nucleus," because the particle is a proton
with "outside the nucleus," because the particle is an electron

Best

with "Outside the nucleus," because the particle is an electron

Other

with "Inside the nucleus," because the particle is a proton

Explanation:

Atom

Atom is smallest component of element which further consist of smaller particles called subatomic particle.

Subatomic particles:

Atom consist of twelve different kinds of subatomic particles but only three are known as Fundamental particles. These three fundamental particles of Atom are

1) Proton

2) Neutron

3) Electron

Both proton and neutron are found in nucleus of Atom and make up atomic mass while electrons revolve around nucleus of atoms in orbitals.

Modern Periodic table is based on atomic number and arrange elements on the basis of their increasing atomic number. Atomic number is number of Protons present inside nucleus or the number of electrons revolving around the nucleus.

Best Answer is:

With "Outside the nucleus," because the particle is an electron

Other

with "Inside the nucleus," because the particle is a proton
