Thermosphere. In this layer, atoms and molecules escape into space and satellites orbit the earth.
No acids have a ph of less than 7 our rain is around a six. dilated water is a 7 and any thing above a 7 is a base
Answer:
Monatomic molecule
Explanation:
Each helium atom has 2 electrons, which is already the maximum no. of electrons that can fit in the first electron shell. When the outermost electron shell is full (2 for the first layer, 8 for others), the atom is stable.
Helium atom itself is already stable, so it doesn't need to combine with another helium atom to form a molecule, hence we call it monatomic.
