The element is likely to be metal.

The substances that are pure and only consists of atoms are called elements. They are the smallest and the fundamental unit of the compound and cannot be split to form any entity.

<h3>What are metals?</h3>

The metals are the elements that are good conductors of charge, electricity, are opaque, malleable, lustrous and ductile. They have high density and melting points. They differ from the non-metals and metalloids based on their physical and chemical properties.

The metals are more likely to donate and gain electrons to form complexes and can produce transitions. The electron gets excited when the energy is given in the form of heat and electricity and thus when comes to the ground state gives a distinct colouration.

Therefore, the element is likely to be metal.
