Give one example of each:
(I) Monovalent cation (2) Bivalent cation
(3) Monovalent anion (4) Bivalent anion
Answers
Answer:
)monovalent anion :Since they now have more electrons than protons,anions have a negative charge. ... 3)A bivalent cation is an cation with an overall charge of +2 and so valence of 2. It is also known as divalent cation
Answer:
For example, Na+ is a monovalent cation, Cl- is a monovalent anion, Ca2+ is a divalent cation, SO42- is a divalent anion, Fe3+ is a trivalent cation, and PO43- is a trivalent anion
Example :- A magnesium ion, Mg2+ is a divalent cation. A bivalent anion is an anion with an overall charge of -2 and so valence of 2.
For example, chloride ions Cl- , bromide Br- , iodide I-. These are monovalent anions, meaning they have a valency (combining capacity) with only one ion of hydrogen. Similarly there are bivalent anions, etc. An ion is an atom (or group of atoms) with an electrical charge. Anions are one of the two types of ions.
