Possible oxidation states are +2,3. How many valence electrons does nickel (ni) have? nickel commonly shows a +2 oxidation state in compounds . Look at the Periodical Table!! Nickel has 2 electrons in its valence (fourth) shell and can lose 2 electrons or gain 6 more electrons to make it stable. The chemical properties of a group are similar because they contain same number of valence electrons and configurations. Electrons have a specific form of distribution (or configuration) in every atom, even Nickel. Therefore, you could conceivably either put 10 dots or 2 dots to represent only the 4s electrons. Nickel ..... [Ar] 3d8, 4s2. valence eletrons are those located in the outer shells; Ni = [Ar] 3d8 4s2. This is because transition metals (most of the metals in the middle of the periodic table) have electrons in both the s shell and the d shell. Valency of nickel = 10. Nickel's Bonding As nickel is a white transition metal and it bonds with non-metallic elements like sulphur, it is known to form an ionic bond. so nickel is conventionally said to have 2 valence electrons. The chemical symbol for Nickel is Ni. but one of the 3d electrons is sometimes elevated in an activated nickel atom Answers: 2 Get Other questions on the subject: Chemistry. Nickel is a silvery-white lustrous metal with a slight golden tinge. In the case of Nickel the abbreviated electron configuration is [Ar] 3d8 4s2. No, Nickel has 2 electrons in its outermost shell! The outer shells of atoms contain what are called valence electrons, which play a large role in electrical and chemical behavior. Name: Nickel: Symbol: Ni: Atomic Number: 28: Atomic Mass: 58.6934 atomic mass units: Number of Protons: 28: Number of Neutrons: 31: Number of Electrons: 28: Melting Point Chemistry, 22.06.2019 04:30, jalalblal. Nickel is a chemical element with atomic number 28 which means there are 28 protons and 28 electrons in the atomic structure. as such it has 2 electrons in its outer shell which may be involved in bonding. valence electrons = 10 electrons (3d8 4s2) hope this helps;-D Some are hard to memorise (or predict), so what is the electron configuration of an atom of Ni? The dot diagram for an element shows the number of valence electrons. In the periodic table, the elements are listed in order of increasing atomic number Z. Electron configuration of Nickel is [Ar] 3d8 4s2. Nickel belongs to the transition metals and is hard and ductile. so. Nickel technically has ten valance electrons, and exhibits oxidation states of +1 through +4, with +2 being the most common. In which … For example, when nickel bonds with oxygen, they trade their electrons. nickel is a transition element. Correction: The first answer was indeed correct.
