Nitrogen (N_2)
B

D
Neon (Ne)
Verified step by step guidance1
Understand the difference between atomic and molecular elements. Atomic elements exist as single atoms in their natural form, while molecular elements exist as molecules composed of two or more atoms bonded together.
Identify the given options: Nitrogen (N_2), Chlorine (Cl_2), Oxygen (O_2), and Neon (Ne). Notice that N_2, Cl_2, and O_2 are diatomic molecules, meaning they consist of two atoms bonded together.
Recognize that Neon (Ne) is a noble gas and exists naturally as single atoms, not bonded to other atoms, making it an atomic element.
Conclude that among the options, Neon (Ne) is classified as an atomic element because it exists as individual atoms rather than molecules.
Remember that most elements on the periodic table are atomic elements, except for a few that naturally form diatomic molecules, such as N_2, O_2, and Cl_2.
