Question

Give one example of each​

Answer 1

1) helium (He)

neon (Ne)

argon (Ar)

krypton (Kr)

xenon (Xe)

radon (Rn)

oganesson (Og)

2) Diatomic molecules consist of two atoms bonded together. In contrast, monatomic elements consist of single atoms (e.g., Ar, He).

3) Examples would include ozone (O3), carbon dioxide (CO2), water (H2O), and hydrogen cyanide (HCN).

4) Examples include H2O, CO2 (pictured) and HCN. O3 ( ozone) is a triatomic.

5) example is sulfur, S8, but red selenium is also an octatomic element stable at room temperature.

Answer 2

Answer:

1)Monomatomic = Helium, Neon.

2) Diatomic= Hydrogen, Nitrogen.

3) Triatomic= CO2

4) Tetraatomic = Tetra

5) Octaatomic = Sulphur.
