The earth's atmospheric helium is replaced by the decay of radioactive elements in the earth's crust. Alpha decay, one type of radioactive decay, produces particles called alpha particles. An alpha particle can become a helium atom once it captures two electrons from its surroundings.
The widely accepted theory of how Earth was formed nearly 4.50 billion years ago is by core accretion. Earth's rocky core formed first, with heavy elements colliding and binding together. Dense material sank to the center, while the lighter material created the crust. Gravity captured some of the gases that made up the planet's early atmosphere. The planet's magnetic field probably formed around this time.
