Step-by-step solution
3 stepsIdentify the atomic numbers for each element.
- W: Atomic number 2 (Helium)
- X: Atomic number 6 (Carbon)
- Y: Atomic number 16 (Sulfur)
- Z: Atomic number 20 (Calcium)
Determine the type of element (metal, non-metal, or noble gas) based on its atomic number and position in the periodic table.
- W (Helium, atomic number 2): This is a noble gas, which is a type of non-metal.
- X (Carbon, atomic number 6): This is a non-metal.
- Y (Sulfur, atomic number 16): This is a non-metal.
- Z (Calcium, atomic number 20): This is an alkaline earth metal.
