Question

When lithium vapours were filled in the discharge tube for anode rays experiment, the anode rays were found to contain only Li$^+$ ions ($A = 7$, $Z = 3$). Each particle of anode ray is, therefore, containing

Answer: C

💡 Solution & Explanation

A neutral Lithium atom ($Z=3, A=7$) has 3 protons, 4 neutrons, and 3 electrons. The Li$^+$ ion has lost one electron, leaving it with 3 protons, 4 neutrons, and 2 electrons. Therefore, correct answer is C.
