Science - Magnesium.
A compound is a substance made of 2 or more elements, chemically bonded together. An element is made of only one type of atom. Mg + O 2 → Mg Oxide Mg + O Mg Oxide Silver/Grey Solid + Transparent colourless gas → White solid powder Observation: I saw a flame appear when the magnesium was inside the bunsen burner flame but then when I took it out it had a really bright white light at the end of the magnesium and it stayed there until all the magnesium turned from a solid into a powdery dust.
