Chapter U2.5, Problem 4E

Interpretation Introduction

Interpretation :

Two non-metals must be listed which combines with three hydrogen atoms to satisfy octet rule.

Concept Introduction :

Octet rule states that elements while forming bonds try to attain noble gas configuration that means those elements try to get eight electrons in the valence shell.

Answer to Problem 4E

Two non-metals are nitrogen and phosphorous which combines with three hydrogen to satisfy octet rule.

Explanation of Solution

Nitrogen and phosphorous are p-block elements of group 15. There are 5 valence electrons. In order to get octet these two elements need three more electrons. Thus nitrogen and phosphorous combines with three hydrogen to satisfy the octet rule.

Conclusion

Nitrogen and phosphorous combine with three hydrogen to satisfy octet rule.
