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). Therefore, each particle of anode contains
Options
A.1 proton only.
B.3 protons and 4 neutrons only.
C.3 protons, 4 neutrons and 2 electrons.
D.3 protons, 3 neutrons and 3 electrons.
Solution
Number of protons = Z = 3
Number of electrons = 3 – 1 = 2
Number of neutrons = A – Z = 4
