Etymology
Ta is the chemical symbol for tantalum, a metal named after the Greek figure Tantalus because the new metal seemed to 'refuse' to dissolve when chemists first tried acids; that's why Ta now stands for a hard metal that resists corrosion. A helpful link is the English verb tantalize, which shares the same root and can remind you that Ta 'teases' acids by not giving in.
