    The ion formed when hydrogen loses one electron.

    Assertion: Radius of the ion is always smaller than the parent atom. Reason: Ion is formed by the loss or gain of electrons by the parent atom.

    Assertion: Mass of a body decreases slightly when it is negatively charged. Reason: Charging is due to transfer of electrons.

    Assertion (A) : When the transition element ionises, the 4s -orbital electrons are removed before the 3d -orbital electrons. Reason (R ) : The energy of 3d -orbital electrons is lower than that of 4s -orbital electrons.
