Which polyatomic ion forms a neutral compound

Acids and Acid Salts 4. Ionic compounds are compounds composed of ions , charged particles that form when an atom or group of atoms, in the case of polyatomic ions gains or loses electrons. Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules. Molecular compounds are electrically neutral. Ionic compounds are usually formed when a metal reacts with a nonmetal or a polyatomic ion. Covalent compounds are formed when two nonmetals react with each other.

Since hydrogen is a nonmetal, binary compounds containing hydrogen are also usually covalent compounds. The charge on the cation is the same as the group number. The cation is given the same name as the neutral metal atom. These elements usually form ionic compounds; many of them can form more than one cation. The charges of the common transition metals must be memorized; Group IV and V metal cations tend to be either the group number, or the group number minus two.

Many of these ions have common or trivial names formed from the stem of the element name the Latin name in some cases plus the ending -ic or -ous. The systematic names also known as the Stock system for these ions are derived by naming the metal first, followed in parentheses by the charge written in Roman numerals.

For the metals below that typically form only one charge, it is not usually necessary to specify the charge in the compound name. The charge on the anion is the group number minus eight. The anion is named by taking the element stem name and adding the ending -ide. Polyatomic ions are ions that are composed of two or more atoms that are linked by covalent bonds, but that still have a net deficiency or surplus of electrons, resulting in an overall charge on the group.

Polyatomic ions are a set of covalently bonded atoms that have an overall charge, making them an ion. For example, the hydroxide ion has the formula OH Hydroxide is a compound made of oxygen and hydrogen that have been bound together. In the process of becoming a compound, hydroxide gained an extra electron from somewhere, making it OH When creating ionic compounds with these polyatomic ions, treat them the same way as typical monatomic ions only one atom.

Parentheses are always used when the compound contains multiples of the polyatomic ion. Boundless vets and curates high-quality, openly licensed content from around the Internet.
