Determine the number of valence electrons and what the atoms charge will be when it forms an ion A. O B. As C.ND.AIE.KPlease leave instructions.​

The valence electron on O = 6, As = 5, N = 5, Al = 3, K = 1Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen's valence electrons as 2s²2p⁴.Similarly we can see that the outermost orbit in As is 4[tex]s^{2}[/tex]4[tex]p^{3}[/tex] hence it has 5 valence electron and the charge on Arsenic ion is +5.The outermost orbit in N is 2[tex]s^{2}[/tex]2[tex]p^{3}[/tex] hence it has 5 valence electron and the charge on Nitrogen ion is 3-The outermost orbit in Al is 3[tex]s^{2}[/tex]3[tex]p^{1}[/tex] hence it has 3 valence electron and the charge on Aluminum ion is 3+The outermost orbit of K is 4[tex]s^{1}[/tex] hence it has 1 valence electron and the charge on Potassium ion is 1+ To know more about valence electronshttps://brainly.com/question/18690146#SPJ1
