Silver (Ag) has 1 valence electron. Valence electrons are the electrons in the outermost shell of an atom, and they play a crucial role in chemical bonding and reactions.
Silver is a transition metal, and its electron configuration is [Kr] 4d10 5s1. The 5s1 electron is the valence electron, which is the electron involved in forming bonds with other atoms.
Understanding the number of valence electrons in silver helps in predicting its chemical behavior, such as its ability to form compounds and its reactivity with other elements.
