The chemical formula \( K_2SO_4 \) consists of the following elements:
- K: Potassium
- S: Sulfur
- O: Oxygen
To determine the number of atoms of each element in the formula \( K_2SO_4 \):
- \( K_2 \): There are 2 potassium (K) atoms.
- \( S \): There is 1 sulfur (S) atom.
- \( O_4 \): There are 4 oxygen (O) atoms.
In summary, the number of atoms of each element in \( K_2SO_4 \) is:
- Potassium (K): 2
- Sulfur (S): 1
- Oxygen (O): 4
