Electron configuration is the "ordering of electrons" in a particular element. Elements have dissimilar properties (both physical and chemical) due to their different electron configuration. Answer and Explanation:1 Element strontium, represented by symbol Sr, has the atomic number 38. It has 38 pro...
What state of matter is natural gas? Which particle of an atom has the least mass? The lightest element is what? What state of matter is sublimation? What is the atomic weight of the lightest element on the periodic table? What state of matter is sand?
The quantum mechanical approach is currently used to explain atomic structure. The study of fundamental constituents such as atoms, molecules, substances, metals, crystals, and other aggregates of the matter is where traditional chemistry begins. Let’s now see about some basic terms of chemistry a...
