What is the definition of multivalent in chemistry?
adjective. Chemistry. having a valence of three or higher.
What elements are multivalent cations?
Ionic compounds with multivalent elements are almost the same as binary ionic compounds, except that the positive ion has more than one possible charge. These ions include copper, gold, iron, and lead.
What is multivalent metallic cations?
Multivalent cations are positively charged metal complexes with a charge greater than 1+. Usually, the cations have the charge of 2+. Common cations found in hard water include Ca2+ and Mg2+. These ions enter a water supply by leaching from minerals within an aquifer.
What does the term multivalent mean?
Definition of multivalent 1 : polyvalent. 2 : represented more than twice in the somatic chromosome number multivalent chromosomes. 3 : having many values, meanings, or appeals.
What is multivalent ionic compounds?
Multivalent Compounds Page 2 What does multivalent mean? • Some metals are multivalent. • This means they have more than one ion form.
What are multivalent interactions?
Multivalent interactions occur when multiple binding groups (e.g., carbohydrates) on one cell bind to multiple copies of a receptor (e.g., a protein) on another cell.
What are all the multivalent elements?

What does multivalent antigen mean?
1. having a valence of two or more. 2. denoting an antiserum, vaccine, or antitoxin specific for more than one antigen or organism; called also polyvalent.
What are multivalent metals?
Transition metals capable of having different charges and forming compounds in different proportions are called multivalent metals, or multiple-charge cations.
What is multivalent bonding?
A cornerstone of biochemistry, particularly in protein-carbohydrate interactions, multivalent bonds comprise a large number of weaker, single connections, allowing multiple hooks or ligands on one surface to entangle with loops or receptors on another.
