Electron configuration

Electrons can be core or valence. The core electrons are like nobel gases and the valance are the rest. Like noble gases, core electrons do not react, but valence electrons do. Imagine, if you will, a reaction of sodium with chlorine gas. The sodium gives up a valence electron and chlorine gains one. The compound made is 1:1 Na:Cl. A similar thing happens with potassium and bromine, you get KBr. The electron configuration of sodium is 1s2 2s2 2p6 3s1. The part up to 2p is just like the nobel gas neon. This is good because noble gas configurations are extra stable. You can write out sodium like this: Na = [Ne] 3s1 and potassium like this: K = [Kr] 4s1. Notice that both have just one electron after the noble gas in an s-orbital. Things that have valence electrons in the s-orbital are said to be in the s-block.…

On page 24 you will find a list of the electron configurations for each of the elements. From this data you can find the total number of electrons, the total number of shells and subshells, as well as how many electrons are in each shell. The large number (the one in 1s2 ) will tell you the shell that the electrons are in. For example, helium (He) has one shell, so its electron configuration is 1s2. Furthermore, the electron configuration tells you what subshell each of the electrons occupy.…

The atomic number to my element is 11, the mass number is 23, the number of neutrons is 12, the protons are 11 and the electrons are also 11, the electron configuration of my element is 1s22s22p63s1. The person who discovered my element is Humphry Davy. He discovered sodium in 1807. Origin of sodium is derived from the English word ‘soda’. The appearance of sodium is soft metal that tarnishes within seconds of being exposed to the air. It also reacts vigorously with water. Used as a…

This sub discipline studies ecosystems. This is evolves in design, construction, monitoring, maintenance, and preservation of ecosystems. The knowledge from this discipline helped me design this machine because i have knowledge of the environment and i'll know what effects the machine would have on organisms. I also was able to make all these systems work in unison because of being able to design and construct them within the machine. Having knowledge of ecological engineering also helped me…

They have one loosely bound electron in their outer shell. Alkali metals also have low ionization energies and that results in their high reactivity and metallic properties. Alkali metals react with nonmetals, especially halligans. Another group is the alkali earth metals. There are not many of them. They are very similar to metals. They also have some similar properties to alkali metals, like their properties depends on how easy the electrons could be lost. The alkali earth metals have two…

Objective The purpose of the experiment is to synthesize multiple cobalt complexes with various ligands and explain the ligand field transitions of these complexes using Ultraviolet-Visible (UV-Vis) spectroscopy. The experiment provides insight into specific colors of certain molecular species and respective bonding information. Introduction Transition elements are defined by the IUPAC as atoms that have an incomplete d-subshell, most commonly referring to the d-block.1 When transition metals…

Phosphorus: General: Phosphorus is one of chemical elements of periodic table with atomic number 15 and atomic mass 30.9738 g/mol. Phosphorus is one of members of polyvalent non-metal of Nitrogen group and can be found in nature as some different allotropic format. Phosphorus can not be found free in nature since it’s so reactive and while it’s isolated and pure, it is clear and almost transparent. Phosphorus can be found in three common forms as white, red and black which their particular…

the number of electrons in the valence shell for an element is clearly seen in this graph. The lowest point of each peak coincides with the Group I alkali metals. From there on, the electron count climbs until a full shell is reached at eight electrons, i.e. the noble gases who have full outer shells. The full shell signals the end of a Period at Group VIII, and then it begins again in Group I in a new Period. There is an anomaly from Scandium (Sc) to Zinc (Zn) where the electron count doesn’t…

2.1 Silicon-Carbide (SiC) Initially, Silicon carbide (SiC) was accidentally introduced by Edward G. Acheson in 1890. Silicon Carbide can be stated as a chemical compound of Silicon and the carbon. Edward G. Acheson was running an experiment on the synthesis of diamonds. At that time, it was produced by a high temperature electro chemical reaction of sand and carbon. We can also find the silicon carbide very rarely in nature in very small amounts. Also Edward G. Acheson was the first person to…

subset amount can be communicated as far as the others.Fundamental amounts are numbers that we have to portray our general surroundings, which we can't express as far as "less difficult," more essential quantities.For examples:My weight is not a crucial amount, since it relies on upon the amount of stuff makes up my body. A decent guess to my weight is only the entirety of the weights of the greater part of the protons, neutrons, and electrons which make me up. On the off chance that I could…
