Which of the subatomic particles are responsible for the differences in isotopes? Protons

Electrons

Atoms

Neutrons

Neutrons

Explanation:

Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.

neutrons

Explanation:

isotopes has the same proton number but different nucleon number because there's different numbers of neutrons in isotopes

it can be icreased by increasing pressure.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
