Wavelength relates to frequency as follows: λ=vf in which f is the frequency, v is the speed of light, and λ is the wavelength.
An atom is the smallest particle of an element that can take part in a chemical reaction.
An atom is made up of energy levels that contain electrons which are negatively charged and the nucleus which contains neutrons and protons that are negatively charge .
Due the positive charge of the nucleus of an atom, an atom always want to attract its electrons and keep them near it however it weakly attracts the other electrons of a nearby atom.
Answer:
0,0,0,0
Explanation:
The formal charge formula:

So:
Hydrogen: 1 elec. of valence and shares two electrons with the O

Oxygen: 6 elec. of valence, 2 lone pairs and shares two electrons with the H and two with the F

Fluorine: 7 elec. of valence, 6 lone pairs and shares two electrons with the O

Oxygen: 6 elec. of valence, 3 lone pairs

Note: the dative bond between F and the second O doesn't count as shared electrons.
