Opposite pairs form ionic bonds, due to this the answer is D - Li and Br; They have unlike charges.
Would all have the same ratio of elements.
The number of protons defines what element it is and also determines the chemical behavior of the element.
Answer:
q= 110.5 ke
Explanation:
Dipole moment is the product of the separation of the ends of a dipole and the magnitude of the charges.
μ = q * d
μ= Dipole moment (1.93 D)
q= partial charge on each pole
d= separation between the poles(109 pm).
e= electronic charge ( 1.60217662 × 10⁻¹⁹ coulombs)
So,
q=
coulombs
q =
e
q = 1.105 * 10⁵ e
q= 110.5 ke
