Explanation:
Because opposites attract, the negative charge at the bottom of the storm cloud wants to link up with the ground’s positive charge. Once the negative charge at the bottom of the cloud gets large enough, a flow of negative charge called a stepped leader rushes toward the Earth. The positive charges at the ground are attracted to the stepped leader, so positive charge flows upward from the ground. When the stepped leader and the positive charge meet, a strong electric current carries positive charge up into the cloud. This electric current is known as the return stroke. We see it as the bright flash of a lightning bolt.
Thunder and lightning occur at roughly the same time although you see the flash of lightning before you hear the thunder. This is because light travels much faster than sound
Answer/Explanation:
Things that will vary include the distribution of electrons between atoms, lone pairs, and bonds, the number of single vs double or triple bonds, and the formal charges on atoms in the structure.
All resonance forms of the same molecule or ion must have the same number of atoms, connected in the same way, and the same number of total electrons.
