Our current model of the atom can be broken down into three constituents parts â protons, neutron, and electrons. Each of these parts has an associated charge, with protons carrying a positive charge, electrons having a negative charge, and neutrons possessing no net charge. In accordance with the Standard Model of particle physics, protons and neutrons make up the nucleus of the atom, while electrons orbit it in a âcloudâ.
Michigan has the longest freshwater coastline in the US and the second longest coast line in the US next to Alaska. There is a comparative table of state shorelines on the Michigan Dept. of Environmental Quality's site that gives the measurements for states touching the Great Lakes.
States shaded white have no coastline. A coastal state is a state in the United States of America that has a coastline or shoreline along a major body of water. There are three oceans that border the United States: the Pacific Ocean (this includes the Gulf of Alaska and the Bering Sea), the Atlantic Ocean/Gulf of Mexico, and the Arctic Ocean (this includes the Chukchi Sea and the Beaufort Sea).
