Which statement correctly states the number of neutrons in the given nucleus? Incorrect If the mass of a lithium nucleus (Z = 3) is 7 amu, then it has 7 neutrons. Incorrect If the mass of a lithium nucleus (Z = 3) is 7 amu, then it has 3 neutrons. Correct: If the mass of a helium nucleus (Z = 2) is 3 amu, then it has 1 neutron. Incorrect If the mass of a helium nucleus (Z = 2) is 3 amu, then it has 2 neutrons. Incorrect If the mass of a helium nucleus (Z = 2) is 3 amu, then it has 3 neutrons
