Polyatomic ion. An electrostatic potential map of the nitrate ion (N O − 3). Areas coloured translucent red, around the outside of the red oxygen atoms themselves, signify the regions of most negative electrostatic potential. A polyatomic ion (also known as a molecular ion) is a covalent bonded set of two or more atoms, or of a metal complex ...
Quaternary ammonium cation. The R groups may be the same or different alkyl or aryl groups. Also, the R groups may be connected. In organic chemistry, quaternary ammonium cations, also known as quats, are positively-charged polyatomic ions of the structure [NR 4] +, where R is an alkyl group, an aryl group [1] or organyl group.
An ion (/ ˈaɪ.ɒn, - ən /) [1] is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention. The net charge of an ion is not zero because its total number of electrons ...
An atom (or ion) whose oxidation number increases in a redox reaction is said to be oxidized (and is called a reducing agent). It is accomplished by loss of one or more electrons. The atom whose oxidation number decreases gains (receives) one or more electrons and is said to be reduced. This relation can be remembered by the following mnemonics.
The bicarbonate ion carries a negative one formal charge and is an amphiprotic species which has both acidic and basic properties. It is both the conjugate base of carbonic acid H 2 CO 3; and the conjugate acid of CO 2− 3, the carbonate ion, as shown by these equilibrium reactions: CO 2− 3 + 2 H 2 O ⇌ HCO − 3 + H 2 O + OH − ⇌ H 2 CO ...
When it comes to classic TV sitcoms, Three's Company, which aired from the late '70s through the early '80s, pretty much tops our list.And Joyce DeWitt as Janet Wood is one of our all-time ...
Nitrate is a polyatomic ion with the chemical formula NO−3. Salts containing this ion are called nitrates. Nitrates are common components of fertilizers and explosives. [ 1 ] Almost all inorganic nitrates are soluble in water. An example of an insoluble nitrate is bismuth oxynitrate.
Ionization can result from the loss of an electron after collisions with subatomic particles, collisions with other atoms, molecules, electrons, positrons, [1] protons, antiprotons [2] and ions, [3][4][5][6][7][8][9] or through the interaction with electromagnetic radiation. Heterolytic bond cleavage and heterolytic substitution reactions can ...
