- Seattle Neighborhoods: Broadview & Bitter Lake — Thumbnail History (historylink.org)
The Broadview neighborhood bordering Puget Sound in northwest Seattle takes its name from the expansive views of Puget Sound and the Olympic Mountains that can be seen from its western slopes. The neighborhood reaches north from N 105th Street to the city limits at N 145th Street, and is bounded on the east by Aurora Avenue N. It is home to Carkeek Park, Evergreen Park Cemetery, the Ida Culver Retirement Home, and Bitter Lake, which beckoned many of the first settlers to the area. It drew its identity from an amusement park called Playland that operated on the south shore of Bitter Lake for 30 years, beginning in 1930. The Seattle-Everett Interurban trolley line ran through the heart of the neighborhood, bringing people and goods to the area and hastening its development. Broadview, once forestland and rural farmland, today is a suburban home to 13,000 residents.
- Zinc (Wikipedia)
Zinc is a chemical element with the symbol Zn and atomic number 30. It is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size. Zinc is the 24th most abundant element in Earth’s crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity (electrowinning).
