Know the Answer?

Moshe Erickson · Answer 1

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 dа ta:

Element 4 is likely to be a non-metal

Element 3 is likely to be a metal

Harper Gonzales · Answer 2

1 and 4.

Explanation:

Hello,

Since nonmetals are located to the right of the periodic table, they have both relatively high ionization energies and high electron affinities, therefore they tend easily gain electrons and toughly lose them. In addition, they have more valence electrons and are very close to accomplish the octate.

In this case, the largest two ionization energies belong to the 1 and 4 elements.

Best regards.
