Covalent compound :- covalent compound are the sharing of electrons two or more atom.
Covalent compound are physical that lower points and compared to ionic .
Covalent compound that contain bond are carbon monoxide (co), and methane .
Covalent compound are share the pair of electrons.
Covalent compound are bonding a hydrogen atoms electron.
Ionic compound a large electrostatic actions between atoms.
Ionic compound are higher melting points and covalent compound.
Ionic compound are bonding a nonmetal electron.
Ionic electron can be donate and received ionic bond.
Ionic compound bonding kl.
Answer:
The wavelength is the distance from the peak of one wave to the peak of the next.
Explanation:
The wavelength of UV light ranges from 10 nm to 400 nm.
We can’t see UV light because our eyes can detect only light with wavelengths between 400 nm (violet) and 700 nm (red).
I think it would be D. atoms because they are very tiny but still take up space
