Salt.
salt
NH4+ is the ammonium radical, which consists of one nitrogen and four hydrogen atoms in an ionized state. It is a compound radical because it has more than one atom. An ion that consists of just one atom, such as Na+ is not a compound.
Compound; there are many types of salts and a salt by definition is a compound formed by replacing hydrogen in an acid by a metal (or a radical that acts like a metal). Table salt however is sodium chloride.
Is a hydrocarbon compound in which one or more hydrogen atoms have been removed. It cannot exist by itself, but will bond with other materials to make new compounds.
No, NaOH is a compound

A zircofluoride is a double fluoride of zirconium and hydrogen, or some other positive element or radical.
An arylene is a bivalent radical produced by the removal of two hydrogen atoms from the benzene ring of an aromatic compound.
Valency is the number of hydrogen atoms that can combine with [or displace] one atom of the element [or radical] to form a compound. For example, one atom of hydrogen combines with one atom of chlorine to form hydrogen chloride [HCl]; so, the valency of chlorine [chloride] is one. Similarly, the valency of the nitrate radical [NO3] in the compound nitric acid [HNO3] is 1, and the valency of the sulfate radical in the compound sulfuric acid [H2SO4] is 2. For elements that do not combine with hydrogen, the valency is the combining power of the element with another element whose valency is known. Valency may also be defined as the number of electrons that an atom donates or accepts to form the duplet state (i.e., 2 electrons in outermost shell) or octet state (i.e., 8 electrons in outermost shell). The valency of an element [or radical] is always a whole number. Elements [or radicals] with valency one are monovalent, those with valency two are divalent, and those with valency three are trivalent
Four carbon atoms and nine hydrogen atoms combine to form the compound butyl or one of its isomers.

Tin ions are positive (cations).
