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.
About 100 miles of Georgia shoreline faces the Atlantic Ocean between South Carolina and Florida. The state extends west and north to the Appalachian Mountains. Small barrier islands lie just off the coast and feature some of the regionâs best beaches. State parks and mountain resorts also boast fine beaches at inland lakes.
