CuSO₄ is the chemical formula for copper(II) sulfate, also known as cupric sulfate. Here's what it's made up of:

* Cu: This stands for copper, a transition metal.

* S: This stands for sulfur, a nonmetal.

* O₄: This represents four oxygen atoms.

In simpler terms:

Copper(II) sulfate is formed when copper ions (Cu²⁺) bond with sulfate ions (SO₄²⁻). This is an ionic compound, meaning it's formed through the electrostatic attraction between positively and negatively charged ions.
