Boiling point of chromium
WebAug 6, 2024 · The boiling point is an important physical property for all materials, even Chromium. Ok but what is the boiling point of an atom of Cr? In the case of Chromium … Chromium is the fourth transition metal found on the periodic table, and has an electron configuration of [Ar] 3d 4s . It is also the first element in the periodic table whose ground-state electron configuration violates the Aufbau principle. This occurs again later in the periodic table with other elements and their electron configurations, such as copper, niobium, and molybdenum. This occurs because electrons in the same orbital repel each other due to their like charges. In t…
