Responses

2 potassium atoms, 1 sulfur atom, and 4 oxygen atoms
2 potassium atoms, 1 sulfur atom, and 4 oxygen atoms

2 krypton atoms, 1 sodium atom, and 4 oxygen atoms
2 krypton atoms, 1 sodium atom, and 4 oxygen atoms

2 barium atoms, 1 silver atom, and 4 oxygen atoms
2 barium atoms, 1 silver atom, and 4 oxygen atoms

2 gallium atoms, 1 silicon atom, and 4 oxygen atoms

Answer 1

The chemical formula K2SO4 consists of the following elements:

- **K** represents potassium.
- **S** represents sulfur.
- **O** represents oxygen.

In the formula K2SO4:
- The "2" before K indicates there are 2 potassium atoms.
- There is no subscript for sulfur, indicating there is 1 sulfur atom.
- The "4" before O indicates there are 4 oxygen atoms.

So, the breakdown is as follows:

- 2 potassium atoms (K)
- 1 sulfur atom (S)
- 4 oxygen atoms (O)

The correct response is:

**2 potassium atoms, 1 sulfur atom, and 4 oxygen atoms.**
