. What is the number of atoms of each element represented by the formula?(1 point)
Responses

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

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

Answer 1

The chemical formula K2SO4 consists of the following elements:

- K (potassium)
- S (sulfur)
- O (oxygen)

In the formula K2SO4, the number of atoms of each element is as follows:

- Potassium (K): 2 atoms
- Sulfur (S): 1 atom
- Oxygen (O): 4 atoms

Therefore, the correct response is:

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