Lightning comes first, and that's when there's an imbalance in electrons between the clouds and ground or from cloud to cloud. The light is the electrons jumping from the cloud to whatever it hits. The thunder happens because of the lightning. The lightning is so hot that it expands the air around it. This air cools just as quickly and the particles slam back together to create the sound.

senojreppihculi, the first answer, is essentially correct. Lightening is essentially static electricity in the million of volts range caused by the formation of rain in thunder clouds. However, lightening can jump from cloud to cloud and ground to cloud, as well as cloud to ground. Lighting also, as senojreppihculi said, causes thunder. The passage of lightening through the air leaves a vacuum. When the lightening is done, the air rushes back in to fill the empty space, the vacuum. This is called an implosion. Big implosions, like big explosions, make big booming sounds, and lightening makes big implosions.
You also might like to know that, since the light from lightening comes to us instaneously for all intents and purposes (approximately 186,000 miles per second) while sound travels much slower (about 740 miles per hour through air at sea level), you can roughly calculate how far away a lightening strike is by counting the seconds from the time you see the lightening to the time you hear the thunder. It's approximately 5 seconds for every mile further away. Thus, if you see lightening and start counting 1,001, 1,002, 1,003, and so on, for every multiple of five, i.e., 5 seconds, 10 seconds, 15 seconds, the lightening is another mile away.
Of course, if you see a bright, blinding flash of lightening and immediately hear "Sissssss, BOO-O-O-OM", duck!

The lightning is a huge spark of electricity. When it strikes the ground the air it travels through is heated to tremendous temperatures which causes air to explode . The temperature is near that of the sun. The explosion is not a chemical reaction except it forms NO2 which is fertilizer it is just air expanding very rapid .
