WHAT'S TRUE. Excessive consumption of spicy snack foods (such as Takis brand corn chips) can lead to stomach pains and gastritis in children. WHAT'S FALSE. Evidence that moderate consumption of such snacks by children carries a significant risk of ulcers or cancer is lacking.
Uranium and the majority of the other heavy elementsâ¦ are formed by stellar nucleosynthesis in novas and supernovas. Heavy elements from the various sources in our galaxy combined with the mass of hydrogen that was the beginning of the formation our solar system around five billion years ago.
Because uranium atoms are so large, the atomic force that binds it together is relatively weak, making uranium good for fission. In nuclear power plants, neutrons collide with uranium atoms, splitting them. This split releases neutrons from the uranium that in turn collide with other atoms, causing a chain reaction.
