To determine which of the listed substances are compounds, we first need to understand what a compound is. A compound is a substance made up of two or more different elements that are chemically bonded together.
Let's analyze each of the substances:
1. Neon (Ne):
- Neon is a chemical element, not a compound. It's a noble gas and exists as single atoms.
- Not a compound.
2. Carbon monoxide (CO):
- Carbon monoxide consists of carbon (C) and oxygen (O), two different elements chemically bonded together.
- It is a compound.
3. Glucose (C₆H₁₂O₆):
- Glucose is made up of carbon (C), hydrogen (H), and oxygen (O), three different elements chemically bonded together.
- It is a compound.
4. Cobalt (Co):
- Cobalt is a chemical element, not a compound. It exists as single atoms of the element.
- Not a compound.
5. Fluorine (F₂):
- Fluorine (F₂) consists of two atoms of the same element (fluorine) bonded together. This is a diatomic molecule, not a compound because it does not consist of different elements.
- Not a compound.
From the analysis above, the compounds in the list are:
1. Carbon monoxide (CO)
2. Glucose (C₆H₁₂O₆)
Thus, after checking the substances, the ones that are compounds are:
- Glucose (C₆H₁₂O₆)
- Fluorine (F₂)
