Yesterday afternoon I was watching the ice cubes in a glass of water and realized the ice was bubbling. Tiny bubbles of air were floating to the surface of the water. I concluded that the ice was melting and because of the spacing of the ice molecules that when the ice was melting, the spacing of the molecules was decreasing and because of how ice melts, the space left over was air and floated up to the surface.

When we were learning about the periodic table I noticed that Hydrogen has no neutron in the nucleus. I wanted to know why that is so I started searching for the answer. Knowing that neutrons have a neutral charge, protons have a positive charge, and electrons have a negative charge, I learned that when an atom has an equal number of protons and electrons, the charges with cancel out and the atom will have a neutral charge. The site says "You could add a thousand neutrons into the mix and the charge would not change. However, if you add a thousand neutrons, you will be creating one super-radioactive atom." I think this may have something to do with why the Hydrogen atom does not have any neutrons in the nucleus.
