The\[H{{D}^{+}}\]ion contains (a) 1 proton, 1 neutron, 1 electron (b) 2 protons, 1 neutron, 2 electrons (c) 2 protons, 2 neutrons, 0 electron (d) 2 protons, I neutron, I electron

Answer:

\[H{{D}^{+}}{{=}_{1}}{{H}^{1}}{{+}_{1}}{{D}^{2}}1\text{ }electron\] \[\therefore \] Total no. of protons \[=1+1=2\] Total no. of electrons\[=1+0=1\] Total no. of neutrons\[=1+0=1\]
