Answer:
Have high melting points and high boiling points.
Explanation:
- Covalent bonds are types of chemical bonds that result from the sharing of electrons between non-metal atoms.
- Covalent bonds result in the formation of covalent compounds.
- Covalent compounds are characterized by low melting and boiling points.
- Therefore, it won't be true to say they have high melting and boiling points.
- Other properties of covalent bonds include poor conductors of electricity and heat, gases or liquids at room temperature, and are non-polar compounds among others.
The atmosphere is a mixture of gasses.
I would say the first three. But I'm not 100% sure. I'm truly sorry if it's wrong
