Valence (chemistry) - Wikipedia The valence is the combining capacity of an atom of a given element, determined by the number of hydrogen atoms that it combines with In methane, carbon has a valence of 4; in ammonia, nitrogen has a valence of 3; in water, oxygen has a valence of 2; and in hydrogen chloride, chlorine has a valence of 1 Chlorine, as it has a valence of one
VALENCE Definition Meaning - Merriam-Webster The meaning of VALENCE is the degree of combining power of an element as shown by the number of atomic weights of a monovalent element (such as hydrogen) with which the atomic weight of the element will combine or for which it can be substituted or with which it can be compared
What Are Valence Electrons? Definition and Periodic Table In chemistry and physics, a valence electron is an electron associated with an atom that can form a chemical bond and participate in a chemical reactions Valence electrons are outer shell electrons for main group elements
Valence Definition in Chemistry - ThoughtCo Valence is how many electrons an atom uses to make bonds with other atoms Different atoms can have more than one valence, depending on the conditions and other atoms nearby Valence numbers do not tell you if an atom will gain or lose electrons, but oxidation states do
4. 4: Valence - Chemistry LibreTexts This capacity is called valence, and it varies periodically with increasing atomic weight The noble gases all have valences of 0 because they almost never combine with any other element H and Cl both have the same valence
Valence (psychology) - Wikipedia Valence, also known as hedonic tone, is a characteristic of emotions that determines their emotional affect (intrinsic appeal or repulsion) Positive valence corresponds to the "goodness" or attractiveness of an object, event, or situation, making it appealing or desirable
