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.
The answer depends on which method you use to determine the coastline. If you use the general coastline method, then Florida has the longest coastline on the Atlantic Ocean with 580 miles. North Carolina is second with 301 miles of general coastline. Maine is third with 228 miles of general coastline. If you use the tidal coastline method, then Maine has the longest coastline on the Atlantic Ocean with 3,478 miles. North Carolina is second with 3,375 miles of tidal coastline and Florida is third with 3,331 miles of tidal coastline.
