In a binary compound, the element that is more positive or basic is typically listed first in the chemical formula. This element is usually a metal or a positively charged ion, while the element listed second is often a nonmetal or a negatively charged ion. The more positive element is usually the one that forms cations in chemical reactions.
Sulfur is an element. Sulfide, the ion formed by sulfur cannot exist on its own as a substance because it carries a negative charge and must be accompanied by a positive ion.
Neither, it is an ion that cannot exist on its own as a substance. It is known as the fulminate ion. It combines with positive ions to form various compounds.
None of them. Cl is the symbol for an atom of chlorine. If it were a compound there would be at least one other symbol, and the same applies to a polar molecule. If it were a negative ion it would be Cl- with the negative sign as a superscript. Chlorine doesn't form positive ions in normal circumstances, but it would be Cl+ , again with the charge as a superscript.
Hydrogen is the element that can form both positive (H+) and negative (H-) ions. When hydrogen gains an electron, it forms a negative ion, and when it loses an electron, it forms a positive ion.
Niether. Hydrogencarbonate is an ion. It does not exist on its own, but must be combined with a positive ion to form a compound.
Lead IV is the 4+ ion formed by the element lead (Pb). Because Pb4+ is a positive ion it must be accompanied by a negative ion.
The element that forms the cation (positive ion) comes first in the formula for an ionic compound.

Neither, it is an ion that cannot exist on its own as a substance. It is known as the fulminate ion. It combines with positive ions to form various compounds.
ClO4 is not a compound, it exists as ClO4-, which is a polyatomic ion called the perchlorate ion. Some positive ion such as potassium or ammonium must be present to balance the charge and form a compound.
A compound because elements are the basic forms of matter which, in this case, would be Hydrogen and Oxygen. Hydroxide is a mixture of the two.
element compound ion
An element like sodium or potassium would form an ionic compound when combined with fluorine. Fluorine is a highly electronegative element that readily accepts electrons to form a negative ion, while elements like sodium and potassium are more likely to lose electrons to form positive ions, resulting in the formation of an ionic compound.
When the positive ion of a base combines with the negative ion of an acid, they form a salt compound. The positive ion from the base combines with the negative ion from the acid through an ionic bond to create a neutral compound known as a salt.
An ion is an atom of any element that either has a positive or negative charge.
