Chemistry when do you use prefixes

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. A binary compound is a compound formed from two different elements.

There may or may not be more than one of each element. A diatomic compound or diatomic molecule contains two atoms , which may or may not be the same.

Metals combine with nonmetals to give ionic compounds. Do NOT use prefixes to indicate how many of each element is present; this information is implied in the name of the compound.

There shouldn't be two vowels in a row. Asked by: Leeanna Arboli asked in category: General Last Updated: 26th February, How do you know when to use prefixes in chemistry? When naming molecular compounds prefixes are used to dictate the number of a given element present in the compound. What does the ending IDE mean in chemistry? These are potent and deadly chemicals. However, since you heard "ide", this changes the whole meaning.

Instead of "sodium, chlorine," the words must have been "sodium chloride," which is table salt. Remember the "ide" means this is a compound made from two elements, in this case sodium and chlorine. What is IDE short for? What does INE mean in chemistry? From Wikipedia, the free encyclopedia. The first is a chemically basic and alkaloidal substance. What is PER in chemistry? Per: 1 Refers to a molecule containing an oxygen-oxygen single bond.

Hydrogen peroxide. Peracetic acid. Isopropyl methyl peroxide. What is a molecular compound? A molecular compound can be defined as a compound where the atoms share electrons through covalent bonds. It is also known as a covalent compound.
