What is the symbol for helium?

The symbol for helium is "He," which is derived from the first two letters of its name. Helium is a chemical element with the atomic number 2 and is a noble gas that is colorless, odorless, and lighter than air. Recognizing element symbols is essential in science as they form a standardized way to convey information about chemical elements in equations and formulas. The other choices represent symbols for different elements: "Ne" is the symbol for neon, "Ar" is for argon, and "Xe" stands for xenon, all of which are unrelated to helium. Understanding the periodic table and the symbols of elements helps in identifying their properties and behavior in chemical reactions.
