Numberof valence electrons =1How may valence electrons are present in sodium with atomic number 11 ? Hint : 1s^(2) 2s^(2) 2p^(6) 3s^(1)
How many chloride ions are present in a 12.4-gram sample of calcium chloride? Ions: Ions are charged substances that posses more electrons than protons. We can form ions from the loss or gain of electrons in an oxidation reduction reaction. Ionic compounds can be formed from thei...
Each electron orbit of the same size or energy (shell) could only hold so many electrons. For example, the first shell could hold two electrons, the second could hold eight electrons, the third could hold 18 electrons, the fourth 32 and so on until reaching the seventh. ...
There are many different ways to produce photons, but all of them use the same mechanism inside an atom to do it. This mechanism involves the energizing of electrons orbiting each atom's nucleus. How Nuclear Radiation Works describes protons, neutrons and electrons in some detail. For example,...
