You can find a list of multiple valences on various chemistry websites, such as the Royal Society of Chemistry or ChemSpider. You can also consult chemistry textbooks or reference books for a comprehensive list.
In chemistry, valence refers to the number of bonds an atom can form with other atoms. It is determined by the number of electrons in the outermost energy level of an atom.
The number of valences an atom can have varies depending on the element. Generally, atoms can have between 1 to 8 valences. For example, carbon has 4 valences while nitrogen has 5 valences.
Yes, an atom can have multiple valences. This is often seen in transition metals, where they can have different valences depending on the reaction they are involved in.
The valence of an atom can be determined by looking at its position on the periodic table and the number of electrons in its outermost energy level. The group number of the element corresponds to the number of valences it has. For example, elements in group 1 have 1 valence, while elements in group 14 have 4 valences.
