An atom with two neutrons, two protons, and two electrons is a helium atom.

Here's why:

* Protons: The number of protons defines the element. Helium has an atomic number of 2, meaning it has two protons.

* Neutrons: The number of neutrons can vary within an element, creating isotopes. The most common isotope of helium has two neutrons.

* Electrons: In a neutral atom, the number of electrons is equal to the number of protons to maintain a balance of charge.
