Check the correct statements regarding a compound and a molecule:
A compound consists of two or more distinct bonded atoms
a molecule may consist of two similar elements chemically bonded
a compound consists of any two or more atoms chemically bonded
a molecule is the smallest chemical subunit of a compound
The correct statements are:
- A compound consists of two or more distinct bonded atoms.
- A molecule may consist of two similar elements chemically bonded.
To check the correct statements regarding a compound and a molecule, we will analyze each statement individually:
1. A compound consists of two or more distinct bonded atoms.
This statement is correct. A compound is a substance composed of two or more different types of elements chemically bonded together. For example, water (H2O) is a compound consisting of two distinct atoms, hydrogen and oxygen, chemically bonded.
2. A molecule may consist of two similar elements chemically bonded.
This statement is also correct. A molecule refers to the smallest unit of a substance that retains its chemical properties. It can be composed of two or more similar or different elements chemically bonded together. An example would be oxygen gas (O2), which consists of two oxygen atoms bonded together.
3. A compound consists of any two or more atoms chemically bonded.
This statement is not entirely accurate. A compound does consist of two or more atoms chemically bonded, but it specifically refers to the combination of different elements. A compound cannot be made up of atoms of the same element. For example, carbon dioxide (CO2) is a compound composed of one carbon atom and two oxygen atoms.
4. A molecule is the smallest chemical subunit of a compound.
This statement is incorrect. A molecule is the smallest unit of a substance that retains its chemical properties, whether it is a compound or a single element. A compound, on the other hand, is a substance formed by the chemical combination of two or more different elements in fixed proportions.
Based on the explanations above, the correct statements are:
- A compound consists of two or more distinct bonded atoms.
- A molecule may consist of two similar elements chemically bonded.
The correct statements regarding a compound and a molecule are:
1. A compound consists of two or more distinct bonded atoms.
2. A molecule may consist of two similar elements chemically bonded.
3. A compound consists of any two or more atoms chemically bonded.
The incorrect statement is:
A molecule is the smallest chemical subunit of a compound.
Explanation:
A molecule refers to a group of atoms bonded together, representing the smallest unit of a chemical compound. However, a compound is a substance composed of two or more different elements chemically bonded together. While a molecule can be a component of a compound, it is not necessarily the smallest subunit. Compounds can be made up of multiple molecules, ions, or both.
