Ionization Energy
H 1 He 2
13.60
Ionization energy is the energy necessary to remove an electron from the electrically-neutral 24.59
atom. It is at a minimum for the alkali metals which have a single electron outside a closed shell,
Li 3 Be 4 increases across each row of the periodic table, reaching a maximum for the noble gasses which B5 C 6 N 7 O8 F 9 Ne 10
have closed shells. Elements with high ionization energy are reluctant to form molecule bonds.

Radioactive Elements
H 1 He 2
A radioactive element is an element that undergoes spontaneous nuclear reactions in which its
. unstable nucleus is made stable through the emission or transformation of protons or neutrons .
in the nucleus. There are nine naturally radioactive elements: uranium, polonium, astatine,
Li 3 Be 4 radon, francium, radium, actinium, thorium and protactinium. All man-made elements heavier B5 C 6 N 7 O8 F 9 Ne 10
. . than uranium are radioactive as well. . . . . . .
