Question

Explain the difference in ionization energies for lithium and hydrogen

Answer 1

Do you know their position in the periodic table

Answer 2

The first ionisation energy is the energy required to remove the most loosely held electron from one mole of gaseous atoms to produce 1 mole of gaseous ions each with a charge of 1+.

The farther you go up the periodic table, like stairs, the tallest step has the most ionization energy. So if you are looking at two elements, and they are in the same row then you would go to see which element is farthest to the right of the periodic table - So from this explanation, you should easily be able to figure this out yourself, if not I can explain more.

Answer 3

Thank you!
