In the highest-numbered shell, the n = 4 shell, there are six electrons. Electrons have a specific form of distribution (or configuration) in every atom, even Selenium. Step-2: We know that the atomic number of selenium is 34.So selenium has 34 protons and 34 electrons as the charge of electrons and protons are equal but opposite in nature.The charge of proton is +1 and the charge of electron is -1. Therefore, six electrons are on its valence shell. To do this it will have to gain 2 electrons, hence the 2- Note: selenium behaves much like sulphur. When electrons are removed from the outermost shell of a calcium atom, the atom becomes a cation that has a smaller radius than the atom. Diana Chan Recipes, It all depends on shells accepting an amount of electrons. Einstein On The Beach Youtube, But in this case, Se has a negative 2 charge, so that means that there are 36 electrons.

The only paramagnetic one is selenium. It is a nonmetal (more rarely considered a metalloid) with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium, and also has similarities to arsenic. Thus, 12-2= 10 electrons. In forming chemical compounds, many elements have a tendency to gain or lose enough electrons to attain the same number of electrons as the noble gas closest to them in the periodic table. The number of electrons is the atomic number added to the charge. So does S. It's easier to gain 2 electrons. How many electrons does selenium gain or lose in forming an ion? Is Chloe Agnew Married, 3. When sodium and chlorine come into contact, each sodium atom gives up an electron to become a Na+ ion, with 11 protons in its nucleus but only 10 electrons (like neon), and each chlorine atom gains an electron to become a Cl− ion, with 17 protons in its nucleus and 18 electrons (like argon), as shown in part (b) in Figure \(\PageIndex{1}\). They are the most unreactive selenium compounds. Samsung Rfg23uers Problems, A)0 B)2 C)4 D)5 E)6.

Selenium can gain 1 electron or loss 2, 4, 6 electrons. After losing four p-electrons, it will gain more stable fulfilled electronic configuration. So, to make selenium to be a stable molecule, it should need to accept 2 electrons. Electrons are negative charge, so the atom becomes a negative 2 charged ion. Similar to sulfide, in aqueous solution, the selenide ion, Se2−, is prevalent only in very basic conditions. Craigslist Alabama Pets, In selenium, the first energy level has two electrons in sub-shell s. The second energy level holds eight electrons. The charges of most monatomic ions derived from the main group elements can be predicted by simply looking at the periodic table and counting how many columns an element lies from the extreme left or right. hexagonal.
