Answer:
Oxygen is the component of air necessary for life on Earth. All living organisms require it for respiration.
The given data is as follows:
Element 1st IE
1 1310 kJ/mol
2 1011 kJ/mol
3 418 kJ/mol
4 2080 kJ/mol
5 947 kJ/mol
Ionization energy is the amount of energy required to remove an electron from an atom. It reflects the tendency of an atom to give away electrons readily. Lower the IE, more easily will the electron be lost. Low values of IE are characteristic of metals whereas, non-metals have higher IE values.
Based on the given data:
Element 4 is likely to be a non-metal
Element 3 is likely to be a metal
