Mar 11, 2017 · The optima electron configuration is the electron configuration of the VIII A family or inert gases. Look at the electron configuration of the nonmetal and how many more electrons the nonmetal needs to achieve the stable electron configuration of the inert gases. Non metals tend to be negative in nature and gain electrons. An electron in a 2s orbital can have the same n, l, and m l quantum numbers as an electron in a 3s orbital. C. Ni has two unpaired electrons in its 3 d orbitals.

Feb 27, 2018 · For example Mg has 2 valence electrons, and thus will give away these 2 electrons to form a 2+ cation. Flourine has 7 valence electrons and thus will take 1 electron to fill its octet, forming a -1 anion. If these two ions combined in a 1:1 ratio, the resulting compound MgF would have a +1 total charge.

Like the other halogens, astatine is a nonmetal, although it shows more metallic character in its chemistry than the others. Astatine and the elements on either side of it, polonium and radon, have no stable isotopes. Too little astatine has ever been present in one place for anyone to actually see it – in fact, since astatine’s boiling ...

Nov 23, 2015 · The electronegativity of an element is a measure of the capacity of the element to attract electrons to itself in bonding with other elements. Electronegativity increases as we move from metallic to nonmetallic in character–that is as we move from left to right across the periodic table. In the first long row, we see a gradual though somewhat uneven increase in electronegativity as we across ... Homework Statement Write the ground state electron configuration of Mn2+. Manganese has an atomic number of 25 and losing two electrons would put it at 23, the same as vanadium (V). Therefore, I thought that the electron configuration would be the same as vanadium
