What is the number 17?
The number 17 is an odd number that comes just after 16 and right before 18. It is a prime number because it can only be divided evenly by 1 and itself. In American politics, Andrew Johnson was the 17th president of the United States. He served from 1865 to 1869 following the assassination of Abraham Lincoln and led the country through the early years of Reconstruction. In science, 17 is the atomic number of chlorine, a chemical element widely used in disinfectants and water treatment. In math, a heptadecagon is a polygon with 17 sides, and it was famously proven to be constructible with a compass and straightedge by Carl Friedrich Gauss.
