The types of elements that form ionic and molecular compounds are to be determined. Concept Introduction: Molecular compounds contain only non-metals which are covalently bonded with each other. Any compound that has at least two different elements is considered to be a molecule. While naming any molecular compound, the name of the first element is written at first, and then the name of the second element is written, followed by a suffix “ide”. Ionic compounds contain atoms of metals and non-metals that are bonded together by an ionic bond formed via transfer of electrons between the atoms.

Answer 1

Question

Chapter 4, Problem 4E

Interpretation Introduction

Interpretation:

The types of elements that form ionic and molecular compounds are to be determined.

Concept Introduction:

Molecular compounds contain only non-metals which are covalently bonded with each other. Any compound that has at least two different elements is considered to be a molecule.

While naming any molecular compound, the name of the first element is written at first, and then the name of the second element is written, followed by a suffix “ide”.

Ionic compounds contain atoms of metals and non-metals that are bonded together by an ionic bond formed via transfer of electrons between the atoms.
