When I was 10, I heard on the radio that one nuclear bomb had destroyed the Japanese City of Hiroshima. This helpled end WWII in 1945

3 PEACE-TIME NUCLEAR REACTOR GENERATES ELECTRICITY

I loved reading ATOMS IN ACTION when I was 14 years old.

The electrical force between the positive nucleus and the negative electrons hold the electrons in orbit.This is much smaller than the nuclear forces between protons and neutrons.

U-235 is Radioactive.

92 protons

143 neutrons

Uranium U- 238 is stable.92 protons

146 neutrons

Plants use the sun’s energy to convert atmospheric carbon dioxide (CO2) into oxygen (O). Where does the carbon (C) go?

13

Wood is made of cellulose, C5 H10 O5, containing: Carbon (C), Oxygen (O ),Hydrogen (H) & Water (H2O) Where else do we find hexagons?

• NUCLEAR REACTORS GENERATE ELECTRICITY without emitting carbon doxide, CO2.

• CO2 is warming our plant with the greenhouse effect from buring gasoline and wood.
