what are zwitterions in chemistry?
238315
A zwitterion is a molecule that has at least two functional groups: one having a positive charge and the other having a negative charge, with an overall charge of zero. Trigonelline is an alkaloid with chemical formula C7H7NO2.

What is the molecular formula of zinc phosphate? The ionic state of Zinc is Zn+2 and the ionic state of phosphate is (PO4)-3. Phosphate molecules need three other atoms or molecular groups to balance and zinc needs two other atoms or molecular groups to balance.

The imbalance of protons and electrons now creates a charge of +3 on the atom. Atoms with a charge are known as IONS. More precisely atoms with a positive charge are known as cations while atoms with a negative charge are known as anions. Boron, above, forms a cation.

Ampholytes are most lipophilic and least soluble in their neutral form. However, zwitterions are always charged; they are rarely lipophilic, and they are often soluble in water at any pH.

Atoms and ions that have the same electron configuration are said to be isoelectronic. Examples of isoelectronic species are N3–, O2–, F–, Ne, Na+, Mg2+, and Al3+ (1s22s22p6). Another isoelectronic series is P3–, S2–, Cl–, Ar, K+, Ca2+, and Sc3+ ([Ne]3s23p6).

In chemistry, an amphoteric compound is a molecule or ion that can react both as an acid and as a base. Many metals (such as copper, zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. ... Amphoteric oxides include lead oxide and zinc oxide, among many others.

Polyatomic Ions. A polyatomic ion is an ion composed of more than one atom. The ammonium ion consists of one nitrogen atom and four hydrogen atoms. Together, they comprise a single ion with a 1+ charge and a formula of NH+4.

ZMA (zinc monomethionine aspartate, magnesium aspartate and vitamin B6) is a supplement used primarily by athletes, gymnasts, and bodybuilders. It was developed by Victor Conte (founder of BALCO Laboratories in Burlingame, California).

We are given that the element Z has a valency of 3. The oxide ion is denoted by O2- and has a valency of 2. So in order to find the chemical formula of the compound, we will cross over the valencies of the two combining atoms. Thus the chemical formula of the substance will be ZO.

However, some elements are capable of forming both cations and anions given the right conditions. One example is hydrogen, which may gain (H-) or lose (H+) an electron, forming hydride compounds such as ZnH2 (where it is an anion) and hydron compounds such as H2O (where it is a cation).

Those ions which are formed from groups of joined atoms are called as polyatomic ions. For Ex:Ammonium ion,Carbonate ion,sulphate ion etc.

Amino acids are generally soluble in water and insoluble in non-polar organic solvents such as hydrocarbons. This again reflects the presence of the zwitterions. In water, the ionic attractions between the ions in the solid amino acid are replaced by strong attractions between polar water molecules and the zwitterions.
