Question

Please explain what does it mean by singly ionized lithium ions ? Would it be different it were fully ionized ( what would that be ). Is there such thing as doubly ionized what would that be ?. And use formula and units for answer

Answer 1

Mass of lithium ions = 7 times 1.66 times 10-27 = 1.162 times 10^-26 kg Because qV = 1/2 mv^2 rightdoublearrow v = squareroot 2qV/m V = squareroot 2 times 1.6 times 10^-19 times 20 /1.162 times 10^-26 = 23.468 times 10^-3 m/s almost equalto 24 km/s Singles ionized means only single electron is removed, doubly ionized means two electrons are removed, and full ionized means all the three electrons are removed
