Proton electron theot

The asymmetry term in semi-empirical mass formula is due to:

• non-spherical shape of the nucleus

• the non-zero spin of the nucleus

• the unequal number of protons and neutrons in the nucleus

• the odd number of protons inside the nucleus

Isotopes of an element:

• A. have the same number of protons and electrons, but a different number of neutrons.

• B. have the same number of protons and neutrons, but a different number of electrons.

• C. have a different number of protons.

• D. have different numbers of electrons.

• E. have the same number of neutrons and protons
