Question

Use the periodic table to identify the elements in the chemical formula K2SO4
. What is the number of atoms of each element represented by the formula?(1 point)
Responses

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

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

Answer 1

The correct identification of the elements in the chemical formula K2SO4 is as follows:

- **K** represents potassium (K), and there are **2 potassium atoms**.
- **S** represents sulfur (S), and there is **1 sulfur atom**.
- **O** represents oxygen (O), and there are **4 oxygen atoms**.

So, the response "2 potassium atoms, 1 sulfur atom, and 4 oxygen atoms" is the correct answer.
