What is positive electrovalency and how is it obtained?
Positive electrovalency is the valency obtained by the loss of valency electrons from the atom of a metallic element in order to complete the outermost orbit. It is obtained when metal atoms lose electrons and acquire a positive charge.
Define electrovalency and explain how it is related to the formation of an electrovalent bond.
Define electrovalency and explain how it is related to the formation of an electrovalent bond.
Electrovalency is the number of electrons lost or gained by an atom during the formation of an electrovalent bond. It is related to the formation of an electrovalent bond as the elements that donate electrons to form positive ions have positive electrovalency, while the elements that accept electrons to form negative ions have negative electrovalency.
Give three examples of elements with positive electrovalency and their corresponding electrovalency values.

Study Notes
Electrovalency
- Electrovalency is the number of electrons an atom gains or loses to form a stable ion, resulting in the formation of an electrovalent bond.
- Electrovalency is a measure of an element's ability to form ions and participate in ionic bonding.
Positive Electrovalency
- Positive electrovalency occurs when an atom loses one or more electrons to form a cation.
- It is also known as the valency of a metal.
Examples of Elements with Positive Electrovalency
- Sodium (Na): electrovalency +1
- Calcium (Ca): electrovalency +2
- Aluminium (Al): electrovalency +3
Negative Electrovalency
- Negative electrovalency occurs when an atom gains one or more electrons to form an anion.
Example of an Element with Negative Electrovalency
- Chlorine (Cl): electrovalency -1
