What is the atomic symbol for lead?

The atomic symbol for lead is represented by "Pb." This abbreviation is derived from the Latin term "plumbum," which is the historical name for lead. In the periodic table, each element has its own unique atomic symbol, typically consisting of one or two letters. The first letter is always capitalized, and if there’s a second letter, it is lowercase.

In the context of this question, "Pb" correctly identifies lead, establishing it as the standard notation used in chemistry and various scientific disciplines. Understanding element symbols is fundamental for recognizing chemical compounds, reactions, and the properties associated with each element. Other options like "Pb2+" indicate a charged ion of lead, while "Ld" is not a recognized symbol for any element, and "Li" stands for lithium, which is a completely different element. Thus, "Pb" is the appropriate choice as it accurately represents the element lead in a simplified and universally accepted format.
