What are univalent atoms?
univalent (not comparable) (chemistry) Having an atomic valence of 1, or having only one valence. Synonym: monovalent. (medicine) Having a vaccine valence of 1. (genetics) Of, or relating to, a chromosome that is not paired with its homologous chromosome during synapsis.
What is a univalent chromosome?
A chromosome that fails to pair with another during the prophase stage of meiosis, and therefore does not exchange genetic information via crossing over. This situation usually occurs in polyploids with an odd chromosome compliment, such as triploids.
What is valence simple?

What is univalent complex analysis?
In mathematics, in the branch of complex analysis, a holomorphic function on an open subset of the complex plane is called univalent if it is injective.
How many homologous chromosomes are in Univalent?
In meiosis I of these flatworms, three homologous pairs of chromosomes form bivalents (chromosomes 1, 3 and 4), and two homologous pairs do not form bivalents, but remain univalent (chromosomes 2 and 5; figure 5).
Which is an example of a univalent element?
Monoxide, mo-nok′sīd, n. an oxide containing a single oxygen atom in combination with two univalent atoms or one bivalent atom. In one series the metals are univalent and the salts have formulas like those of the sodium salts. Silver acts as a univalent element and calcium as a divalent element in…
Can a divalent element combine with a univalent element?
A divalent element, on the other hand, will combine with two atoms of a univalent element. Silver acts as a univalent element and calcium as a divalent element in the formation of their respective nitrates and chlorides.
How does a univalent element form two series of salts?
The element forms two series of salts in which it acts as a metal: in the aurous series the gold is univalent, the chloride having the formula AuCl; in the auric series it is trivalent, auric chloride having the formula Finally one atom of a tetravalent element such as carbon will combine with four atoms of a univalent element, as in the compound
Which is an example of a univalent metallic radical?
In these two compounds the group of atoms, BiO, acts as a univalent metallic radical and is called _bismuthyl_. The element forms two series of salts in which it acts as a metal: in the aurous series the gold is univalent, the chloride having the formula AuCl; in the auric series it is trivalent, auric chloride having the formula
