No, element is a unique existing in the universe. But elements are made up of sub atomic particles. Some sub atomic particles have mass and some other don't have. So simplest form of matter is the photon whose rest mass is zero. Yet it has momentum. That is the quantum of energy. Energy is the ultimate reality.
It is an element.
Element
The simplest form of all matter is an atom, which consists of a nucleus made up of protons and neutrons, surrounded by electrons. Atoms combine to form molecules and compounds, which make up all substances in the universe. Elements, defined by the number of protons in their nuclei, are the building blocks of matter, with each element representing a unique type of atom.

No, an element is the simplest form of matter.
Correct answer= "Element" Element is the simplest type of matter; the basic unit from which all other matter is built
It is an element.
an element
The simplest form of matter is an atom. Atoms are composed of protons, neutrons, and electrons.
Neptunium itself is an element, the simplest form of matter.

Atoms
The simplest form of an element is an atom. Subatomic particles are not a form of the element; they are a "building block" of an element.
An atom is the simplest form of matter that has a unique set of properties. Each type of atom is characterized by a specific number of protons in its nucleus, which determines its chemical properties.
The most chemically simple form of pure matter is that of a pure element, not chemically bonded in any way.
