A helium atom is the simplest atom after hydrogen, consisting of two protons and two neutrons in its nucleus, with two electrons orbiting around it. It is the second element on the periodic table, represented by the symbol He. The two protons give it a positive charge, balanced by the negatively charged electrons. Helium is a noble gas, meaning it is chemically inert and rarely forms compounds because its outer electron shell is full. It is colorless, odorless, and lighter than air, often used in balloons, cooling systems, and even in nuclear fusion research. -by JATIN SHARMA
