What is the wind chill temperature, if the temperature is -100F and the wind speed is 40 mph? How long would it take to get frostbite?

Both models are effective because they show the valence electrons, and these valence electrons indicate the reactivity of an element.

The atomic nucleus made up from protons (yellow) and neutrons (blue) and held together by nuclear forces. nuclear forces (also known as nuclear interactions or strong forces) are the forces that act between two or more nucleons. they bind protons and neutrons (“nucleons”) into atomic
