Valence electrons are important when drawing molecular structures because a. They are closest to the nucleus of the atom and do not participate in chemical
bonding
b. They are closest to the nucleus of the atom and participate in chemical
bonding
c. They are farthest away from the nucleus of the atom and do not participate in
chemical bonding
d. They are farthest away from the nucleus of the atom and participate in
chemical bonding

d

Explanation:

Valence electrons are in the outermost shell. They form chemical bonds with other elements, not any other electrons. Hope this helps!

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

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".
