Full origin of valence →Frequently asked questions
What is the difference between valence and valency?
They are the same term in different spellings. 'Valence' is standard American usage and is now common everywhere in chemistry, while 'valency' remains usual in British scientific writing. Neither is wrong.
What are valence electrons?
They are the electrons in an atom's outermost shell. Because they are the ones available for bonding, they determine almost all of an element's chemical behaviour and its position in the periodic table.
What does valence mean in psychology?
It means how positive or negative an emotional experience or stimulus feels. A photograph of a puppy has positive valence and a photograph of an injury has negative valence, independent of how intense, or arousing, the reaction is.
