Notice that we may now write the formula for the cross product as. Example 1: The cross product of the vectors and. Solution: Properties of the Cross Product: 1. The length of the cross product of two vectors is. 2. Anticommutativity: 3. Multiplication by scalars: 4. Distributivity: 5.
Best Answer: Hydrogen and Helium. Not only are they the most abundant elements in the Sun, they're also the most abundant elements in the universe.
Helium is the second most abundant element in the universe. Only hydrogen occurs more often than helium. Helium is also the second simplest of the chemical elements. Its atoms consist of two protons, two neutrons, and two electrons. Only the hydrogen atom is simpler than a helium atom. The hydrogen atom has one proton, one electron, and no neutrons. Helium was first discovered not on Earth, but in the Sun.
