Question 3

A lithium-6 atom is singly ionized to form a 36Li+^{6}_{3}\text{Li}^+36​Li+ ion.

Which of the following correctly identifies the constituent particles of the nucleus of this ion, and the specific charge of this nucleus?

Use the following values from the datasheet:

  • Proton mass, mp=1.67×10−27 kgm_p = 1.67 \times 10^{-27}\text{ kg}mp​=1.67×10−27 kg
  • Neutron mass, mn=1.67×10−27 kgm_n = 1.67 \times 10^{-27}\text{ kg}mn​=1.67×10−27 kg
  • Elementary charge, e=1.60×10−19 Ce = 1.60 \times 10^{-19}\text{ C}e=1.60×10−19 C
A

Constituents: 3 protons, 3 neutrons; Specific charge: 4.8×107 C kg−14.8 \times 10^7\text{ C kg}^{-1}4.8×107 C kg−1

B

Constituents: 3 protons, 3 neutrons; Specific charge: 1.6×107 C kg−11.6 \times 10^7\text{ C kg}^{-1}1.6×107 C kg−1

C

Constituents: 3 protons, 3 neutrons, 2 electrons; Specific charge: 1.6×107 C kg−11.6 \times 10^7\text{ C kg}^{-1}1.6×107 C kg−1

D

Constituents: 3 protons, 3 neutrons, 2 electrons; Specific charge: 4.8×107 C kg−14.8 \times 10^7\text{ C kg}^{-1}4.8×107 C kg−1
