D. all of these can produce nuclear energy
It gains or loses electrons to become like the Noble gases having 8 valence electrons to become the most stable.
I don’t know about 3 but I know that 4 is solid, 5 is you’ll feel the vibration first, 6 is you’ll see the lightning first because the speed of light is faster than the speed of sound and 7 is sound waves need a medium to travel and light waves don’t, sound waves are longitudinal and light waves are transverse, and sound waves are mechanical waves while light waves are electromagnetic waves
I'm not sure, but maybe burning point...
