Yes - too many to name - but potassium permanganate would be one and Manganese dioxide another.
no, it does not exist
Nitrogen in any pure form is an element, not a compound. However, at standard temperature and pressure, nitrogen exists predominantly as divalent molecules.
An "Oxidised Element" is any element that has reacted with Oxygen to form a compound. The compound suffixes of these compounds will be "Oxide, Monoxide, Dioxide, Trioxide" etc. Some examples of oxidised elements:Iron + Oxygen --> Iron OxideCarbon + Oxygen --> Carbon DioxideMagnesium + Oxygen --> Magnesium Oxide
Elements of group 18 are least reactive.These are noble gases.They are unlikely to have a reaction with any element or compound.
A bismuthide is any compound of bismuth with a more electropositive element.
Since manganese is a metallic element, its oxidation number in metallic form is 0, as for any other element.
Carbon is not made form any compound. It is an element composed only of carbon atoms.
because it is extremely unreactive towards any element including oxygen to form a compound
we can combine any other element or even an compound witw it like hydrogen+oxygen=water
no, it does not exist
Any metallic element will form an ionic compound with fluorine. ("Flourine" is not a chemical name!) Examples of metals are sodium, magnesium, lanthanum, and iron.
A compound: any formula that contains more than one kind of atomic symbols represents a compound.
Any element except helium and possibly neon can form some compound.
It is a compound because at the start of any element is a capital letter so there are 4 elements in this compound
A term used to describe any element or compound is called a substance or substances.
Carbon is the element tht will form only covalent compound.
There is no such thing as a compound element. Something cannot be both an element and a compound Neon is an element and so is made of nothing but neon. Neon does not form any compounds.
