Answer:

Calcium + Oxygen = Calcium Oxide

Step-by-step explanation:

Calcium basics: -positively charged ion (cation) -99% in bones and teeth, 1% in extracellular fluid. -important for bone and tooth formation, normal cell function, and neural transmission.

Oxygen, a colourless, odourless, tasteless gas essential to living organisms. It will support life. It is noncombustible, but will actively support the burning of combustible

Symbol: O

Atomic mass: 15.999 u

Atomic number: 8

Electron configuration: [He] 2s²2p⁴

Electrons per shell: 2, 6

Melting point: -218.8 °C

Calcium reacts with oxygen to form calcium oxide. The chemical equation for this reaction is Ca + O2 → CaO.
