How many electrons are in an ion with 54 electrons and a − 1 charge?
Because the sum of the numbers of protons and neutrons equals the mass number, 127, the number of neutrons is 74 (127 − 53 = 74). Since the iodine is added as a 1− anion, the number of electrons is 54 [53 – (1–) = 54]. Check Your LearningAn ion of platinum has a mass number of 195 and contains 74 electrons.
What is barium in?
Barium is a soft, silvery metal that rapidly tarnishes in air and reacts with water. Barium is not an extensively used element. Most is used in drilling fluids for oil and gas wells. It is also used in paint and in glassmaking.
