• why does nickel have 10 valence electrons

  Chemistry. For example, does zinc have 2 valence electrons or 10? Nickel has a long history of being used in coins. c. Silicon. The reason it has 10 is because nickel is a transition metal, so the d and s electrons can participate in chemical bonding. 1. Because of shielding, the nucleus has less control over this 6s 1 electron than it does over a 3s 1 electron. Also, why does Al have a +3 charge? Correction: The first answer was indeed correct. For nickel, this would be argon. You take your valence electrons as everything after the noble gas configuration. Nickel has 10 valence electrons. - 13131212 1. Log in. Thus, although a nickel atom has, in principle, ten valence electrons (4s 2 3d 8 ), its oxidation state never exceeds four. Al, Mg, Li. New comments cannot be posted and votes cannot be cast. Press J to jump to the feed. There are only 2 electrons in the 4 shell, so the number of valence electrons for Ni is 2. Is the valence … As nickel is a stronger atom than … Join now.

Please do not post entire problem sets or questions that you haven't attempted to answer yourself. If it was a question ? how does atomic radius change from left to right across a period in the periodic table? a. 5 points How many valence electrons does a Nickel have? Related questions. Because the 4s orbital is lower in energy than the 3d orbital, Ni's first two valence electrons can be placed in the 4s orbital. Answer link. Atomic … This question confuses me because 4 is a bigger number than 3, however part of the third shell is higher in energy than part of the fourth shell. The first reply is not entirely correct. Since elements in the same family have the same number of valence electrons, their dot structures will look the same, too! Get more help from Chegg. In the case of Nickel, n = 4 is the highest QN and contains 2 electrons (max allowed) in the s-orbital.

How many valence electrons does nickel have? So for example, Zinc would have 12 valence electrons … Also, how would you determine the valence electron configuration for these elements? Ni most commonly forms compounds with a +2 oxidation state, but compounds from -2 to +4 are known. I am not sure where you found two (maybe you could link). It is not a molecule. So neither 2 nor 10 valence electrons really reflects the chemistry of Ni. The neutral atom has two electronic configurations that have similar energy: [Ar]3d⁸4s² and [Ar]3d⁹4s¹; … A valence electron is an outer shell electron and may participate in the formation of a chemical bond. I put the answer as 10 but my teacher marked it incorrect. Expert Answer . The rule is based on the fact that the valence orbitals of transition metals consist of five d orbitals, one s orbital and three p orbitals which can collectively accommodate 18 electrons as either bonding … In the case of Nickel the valence electrons is 0,1,2,3. d.Ni lDX ls nte i i n . How many valence electrons does nickel have? Although Copper only has one true valence electron, it is a transition metal, so can use some inner-shell electrons for chemical bonding.

The 18-electron rule is a chemical rule of thumb used primarily for predicting and rationalizing formulas for stable transition metal complexes, especially organometallic compounds. Neon has 10 electrons --- 2 in the first shell, and 8 in the second shell (so eight valence electrons). Remember that after the first electron is added, though, … Chemistry The Periodic Table Valence Electrons. This is because the element's atomic number is 13, reflecting the fact that it has 13 electrons and 13 protons. Yes, the number of valence electrons is the number of electrons in the outermost shell and the electron configuration of Ni is [Ar] 3d^8.4s^2. Zincs ground state electron configuration, with all numbers in parenthesis as exponents, is 1s(2)2s(2)2p(6)3s(2)3p(6)4s(2)3d(10). Because of quantum interactions, metal atoms all share their outer electron. Hello! Nickel has eight electrons in the 3d orbital and two electrons in the 4s orbital, which means nickel has 10 total valence electrons.
