It isn't a element, as an element is one atom. It would be a compound if the elements chemically combined, but if they didn't, its a misture
Mercury is an element, which means the smallest unit is a single atom.
an atom
Not in and of itself. Ozone is a form, or allotrope, of the element oxygen.
Mercury is a metal element. Mass number of it is 200.
No. Nitrogen and oxygen are two different elements. The identity of an element is determined by the number of protons in the nucleus. A nitrogen atom has 7 protons while an oxygen atom has 8. Isotopes are variations of the atoms of a given element that differ in the number of neutrons in the nucleus.
no oxygen is an element of one atom and that's an oxygen atom
Oxygen is a neutral atom element.
Oxygen is a neutral atom element.
it is a non- metal element.
Well, honey, Mercury might be a planet, but it ain't no diatomic element. Diatomic elements are those that naturally exist as molecules composed of two atoms bonded together, like hydrogen or oxygen. So, Mercury can keep spinning around the sun, but it ain't gonna be part of the diatomic club anytime soon.
Oxygen is an example of an atom, gas, and an element.
