Answer:
D. Cr
Explanation:
In order to determine which atom has at least one electron in its d orbital, we have to write their theoretical electron configurations.
- ₁₉K 1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹
- ₂₄Cr 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁴
Cr has 4 electrons in d orbitals. Cr belongs to the d-block in the periodic table.
Explanation:
8% 9:30 pm The binding energy B is the energy associated with the mass difference between the Z protons and N neutrons considered separately and the nucleons bound together (Z+N) in a nucleus of mass M. The formula is B = (Zm, + Nm, - M)c², where mp and m, are the proton and neutron masses and c is the speed of light.
Answer:
Electromeric effect refers to a molecular polarizability effect occurring by an intramolecular electron displacement (sometimes called the 'conjugative mechanism' and, previously, the 'tautomeric mechanism') characterized by the substitution of one electron pair for another within the same atomic octet of electrons.
