What is a univalent cation and a trivalent cation?
The 'valency' of a cation describes the free orbitals it has to accept lewis electrons. For example, potassium is monovalent (or univalent), and only has one empty orbital to accept electrons, whereas calcium is divalent, and has two empty orbitals, (and a 2+ charge) to accept donor electrons for lewis bonding.
What happens when divalent impurity is doped with trivalent element?
will there be any structural changes when divalent is doped with trivalent
WHAT IS OXIDATION NUMBER OF MGCO3?
Magnesium and carbonate are divalent.
What are examples of divalent metal?
Fe 2+ , 3+
Is calcium monovalent?
NO, Calcium is divalent. It is having 2 valence electrons
What ion will Strontium form?
Strontium form the divalent cation Sr2+.
What is the total charge of radium?
Radium is a divalent chemical element; the cation is Ra2+.
Which elements form a divalent cation and which elements form a trivalent anions?

What is the common ion for cadmium?
Cadmium has a divalent cation: Cd2+.
What kind of ion does magnesium form?
Mg ^ 2+ :D
Will copper replace magnesium in compounds?
Not by electromotive action; magnesium would replace copper instead. However, a divalent copper cation conceivably could replace a divalent magnesium ion in a complex mineral such as a silicate or aluminate.
Why beryllium can polarise any anion that it is bonded to?
This is largely due to the small ionic radius and divalent charge of a beryllium cation. This combination gives it the strongest electric field at its surface of any metal cation.
An atom that has lost two electrons is called?
This atom become a cation with the electrical charge +2.
What type of ion is magnesium?
Magnesium can only exist in its 2+ state of a cation ( Mg2+).
Chromate an anion or cation?
Chromate is an divalent anion with formula CrO4-2
What is the formula for calcium dilhydrogen phosphate?
According to Wikipedia, Ca(H2PO4)2: Calcium forms a divalent cation, and the polyatomic anion dihydrogen* phosphate has only a single negative valency.
What is a univalent cation and a trivalent cation?

For example, potassium is monovalent (or univalent), and only has one empty orbital to accept electrons, whereas calcium is divalent, and has two empty orbitals, (and a 2+ charge) to accept donor electrons for lewis bonding.
