Which pair of elements would form a nonpolar covalent bond? a. bismuth and sulfurb. carbon and oxygenc. nitrogen and oxygend. silicon and phosphoro

Answer is: D.silicon and phosphorus.

When the electronegativity difference is greater, the bond polarity is increasing..  

Electronegativity (χ) is a property that describes the tendency of an atom to attract a shared pair of electrons.  

Atoms with higher electronegativity attracts more electrons towards it, electrons are closer to that atom.  

A) Δχ(Bi-S) = 2.5 - 2.0 = 0.5; polar covalent.

B) Δχ(C-O) = 3.5 - 2.5 = 1.0; polar covalent.

C) Δχ(N-O) = 3.5 - 3 = 0.5; polar covalent.

D) Δχ(Si-P) = 2.2 - 1.9= 0.3; nonpolar covalent.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
