Atomic number = 50, mass number = 118 When referring to an atom, we simply use the element’s name: the term sodium refers to the element as well as an atom of sodium. But it can be unwieldy to use the name of elements all the time. Instead, chemistry defines a symbol for each ...
Bright krypton-lamps cast a white glare on the sullen convicts as they passed across the main court of the prison to the massive cell-houses. Overhead droned fishlike Planet Patrol cruisers, keeping watch upon the moon. Ul Quorn’s column trudged into its own cellhouse, down a bleak cement...
even though those orbitals belong to a shell of lower principal quantum number. Thus, after argon, the next electron enters the 4sorbital, not a 3dorbital, giving the configuration [Ar]4s1forpotassium, where [Ar] represents the configuration of argon. Indeed, potassium is similar in chemical ...
