To determine which substances from the given list are compounds, we need to examine the nature of each substance. A compound is a chemical substance that contains two or more different elements chemically bonded together.
Let's analyze each substance:
1. Neon (Ne)
- Neon is a noble gas and exists as a single element.
- \(\Rightarrow\) Neon is not a compound.
2. Carbon monoxide (CO)
- Carbon monoxide consists of one carbon atom chemically bonded to one oxygen atom.
- \(\Rightarrow\) Carbon monoxide is a compound.
3. Glucose \(\left( C _6 H _{12} O _6\right)\)
- Glucose is composed of six carbon atoms, twelve hydrogen atoms, and six oxygen atoms, all bonded together in a defined structure.
- \(\Rightarrow\) Glucose is a compound.
4. Cobalt (Co)
- Cobalt is a single element.
- \(\Rightarrow\) Cobalt is not a compound.
5. Fluorine \(\left(F_2\right)\)
- Fluorine as \( F_2 \) is a diatomic molecule consisting of two fluorine atoms bonded together.
- \(\Rightarrow\) Fluorine is a compound.
Summarizing the findings:
- Neon is not a compound.
- Carbon monoxide is a compound.
- Glucose is a compound.
- Cobalt is not a compound.
- Fluorine is a compound.
Therefore, the substances that are compounds are:
- Glucose
- Fluorine
