Document Summary

Because nuclear charge from bottom to top in a chemical family: francium is the most reactive element out of helium, radon, francium, hydrogen and ununoctium, electronegativity is derived from reactivity, element y is likely a group 2 element. Electronegativity is the measure of attraction between a nucleus and electrons in a bond. It decreases as you go down the periodic table due to the greater number of outer shell electrons, which are further away from the nucleus. Electronegativity stays generally the same going down a row of the periodic table. But going down a periodic table, electronegativity increases due to greater atom size. (and therefore, greater number of electrons. ) Ionization energy is the quantity of energy required to discharge an electron. It is a function of atomic radius and the larger that radius is, the smaller amount of energy is required to remove the electron from the most outer orbit.
