HQ7.45 Homework . Unanswered Identify the period 2 element from the following ionization energies. IE, 13.6 eV IE, 35.1 ev TE IE 54.9 ev 77.4 eV TE IE IE, E 113.4 eV 138.1 eV 739.3 eV 871.4 eV

Answers

According to the given pattern of ionization energies , first 6 electrons are removed easily with less ionization energies. Ionization energy increases drastically for 7th electron i.e. 7th electron must have been removed from a highly stable Noble gas configuration.

This element has 6 electrons in valence shell.

Only oxygen atom in period 2 has 6 electrons in valence shell.

Hence this element is Oxygen.

Answer -- oxygen
