To determine whether people have worked enough to meet the requirements, the SSA requires people to earn a certain number of work credits. Work credits are essentially income that is assigned a value. In general, you must have accumulated 40 work credits (20 in the past 10 years) to be eligible for disability.
Bromine is a chemical element with symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas. Its properties are thus intermediate between those of chlorine and iodine.
What is the electron configuration for bromine? [Ar] 4s2 3d10 4p5 (abbreviated) Br: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p5 (whole) Shown with the 4s2 energy level below the higher energy level of 3d10 ( as you would learn it â¦in college ), but you could order them numerically/energy level if you wanted to. 3d10 4s2.
