Let's solve the problem step by step and fill in the blanks based on the descriptions provided.
1. Type of molecule only has 2 atoms
- A molecule with only 2 atoms is called a
diatomic molecule.
- Example: \( \text{O}_2 \) (oxygen), \( \text{H}_2 \) (hydrogen).
2. Molecules generated two kinds of bonds
- Molecules that have both
ionic bonds and
covalent bonds are called
polyatomic ions or
molecular compounds with ionic properties.
- Example: \( \text{NH}_4^+ \) (ammonium ion).
3. A single-atom, the covalent-bond-free molecule is referred to as _______
- A single atom that does not form covalent bonds is simply called an
atom.
- Example: \( \text{He} \) (helium).
4. Molecule is made up of two or more different elements or compounds that have been physically mixed
- When two or more different substances are physically mixed but not chemically bonded, it is called a
mixture.
- Example: Saltwater (a mixture of salt and water).
5. Formed from atoms that are two or more distinct elements together in a consistent weight ratio. It is possible to decompose it chemically into a simpler form of matter
- A substance formed from two or more distinct elements in a consistent weight ratio is called a
compound.
- Example: Water (\( \text{H}_2\text{O} \)).
6. The term ______ was used to name substances composed of two or more atoms, whether they are from the same atom or distinct ones
- Substances composed of two or more atoms are generally called
molecules.
- Example: \( \text{O}_2 \) (oxygen molecule), \( \text{CO}_2 \) (carbon dioxide molecule).
Final Answers:
1.
Diatomic molecule
2.
Polyatomic ion/molecular compound with ionic properties
3.
