Chapter 6, Problem 59A

Interpretation Introduction

Interpretation:

An element forms a negative ion. The location of the element in the periodic table needs to be determined.

Concept introduction:

A periodic table consists of groups and periods. The horizontal rows are termed as periods and the vertical rows are termed as groups. The elements with similar properties are placed together in a group.

Answer to Problem 59A

The elements on the right side of the periodic table tend to form a negative ion when ionized because they are non-metals.

Explanation of Solution

The elements that form negative ions on ionization are called anions. The elements on the right-hand side of the periodic table fulfill the octet rule by gaining of electrons while the elements on the left lose electrons and form cations to fulfill the octet rule.

Therefore, elements on the right side of the periodic table tend to form a negative ion when ionized.

Conclusion

The elements on the right side of the periodic table tend to fulfill the octet rule by gaining of electrons.
