Concept explainers
A substance that ____ is considered to be a chemical compound.
- a. contains at least two different elements
- b. contains at least two atoms
- c. has a
chemical bond - d. has a stable valence shell
- e. has covalent bonds
Introduction:
Substances are made up of chemical components that are composed of either the same elements or different elements. It may be in different forms such as solid, liquid, and gaseous state.
Answer to Problem 1TYR
Correct answer:
A substance that contains at least two different elements is considered to be a chemical compound. Therefore, option a is correct.
Explanation of Solution
Justify reasons for the correct statement:
Substances that are composed of two or more different elements are said to be chemical compounds. Option (a) is given as “contains at least two different elements”. Hence, option (a) is correct.
Justify reasons for the incorrect statements:
Option (b) is given as “contains at least two atoms”, it is said to be diatomic in nature. Hence, it is a wrong answer.
Option (c) is given as “has a chemical bond” all atoms are joined by a chemical bond. Hence, it is a wrong answer.
Option (d) is given as “has a stable valence shell”. It is the outermost orbital of an atom. Hence, it is a wrong answer.
Option (e) is given as “has covalent bond”. It is defined as the chemical bond that shares two electrons of two different atoms. Hence, it is a wrong answer.
Hence, options (b), (c), (d), and (e) are incorrect.
Substances are made up of at least two different elements in a chemical component. Elements are linked by chemical bonds with different atoms. Substances may be in three different phases.
