Answer to Question #159560 in General Chemistry for John

Question

Research and tabulate values of first ionisation energy for the elements in groups 1 and 2 of the periodic table.

 Plot graphs of first ionisation energy of the elements of groups 1 and 2 on the same axis.

Answer 1

IONISATION ENERGY

This page explains what first ionisation energy is, and then looks at the way it varies around the Periodic Table - across periods and down groups. It assumes that you know about simple atomic orbitals, and can write electronic structures for simple atoms. You will find a link at the bottom of the page to a similar description of successive ionisation energies (second, third and so on).
