Nickel is in group 10 of the periodic table and represents one of the transition metals. Transition metals are named for their ability to form covalent bonds using electrons from two shells located about the atom's nucleus. What are the properties of nickel?
The electronegativity of Krypton is: χ = 3 In general, an atom’s electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. The higher the associated electronegativity number, the more an element or compound attracts ...
