Noble gases have a full outer shell, meaning that they have complete electrons in their outer shell. This complete number varies. For instance, the outer shell of Helium has 2 valence electrons while the outer shell of Xenon has 8 electrons. Nowadays, there remains to be a few noble gases...
What is noble gas notation? Electron Configuration: The current model of the atom is the quantum mechanical model. In this model, each element has a unique electron configuration. Noble gases are the family of elements that are nonreactive because their valence electrons are full. ...
has two electrons in its outermost shell. by losing two electrons from its m shell its l shell becomes the outermost shell that has a stable octet . the nucleus of this magnesium atom still has twelve protons but the number of electrons has decreased to ten. so, a net positive charge is...
Each element has its own unique electron configuration. Its electron configuration tells us where the most likely location to locate its electrons in the electron cloud. The components of an electron configuration tell us the distance the electron is from the nucleus, the shape of the orbital it...
When that happens, the original element drops down to a full shell and the second electron completes its upper shell; both elements are now stable. However, because the number of electrons and protons in each element are no longer equal, the element that received the electron now has a net...

Since an atom contains equal number of protons and electrons, it has no overall charge: the positive charges on all the protons are exactly balanced by the negative charges on all the electrons. But sometimes an atom can gain or lose an electron to become what's called an ion. If it ...
Oxygen can form ionic compounds with metals. When it does it becomes an oxide ions which have a charge of -2. Some oxides are highly significant such as Iron II oxide which is commonly called rust. Electron Configuration: Originally the electrons associated with an atom were viewed as bein...
(GOD in the trade) and the release of electrons as a measurand. Our sensors used a similar lateral flow principle and voltametry and when I described the process to investors their response was often. “Could this work on blood glucose?” The reason they gave for asking this was that ...
has 8 electrons then the element is said to have a complete octet. by gaining, sharing and losing the electrons the atoms complete their outermost orbital and make an octet. the capacity of an atom is described by the total number of electrons lost, gained or shared to complete its octet ...
