Sulfur has six valence electrons and potassium has one valence electron. The electronegativity difference between the two elements is 1.76.
How can the octet rule be used to explain the bonding of potassium and sulfur?

A. Sulfur needs access to two electrons to reach a full octet. Each potassium atom has one valence
electron that it prefers to lose to obtain a full octet. Therefore, two potassium
atoms share
electrons and form a covalent bond.

B. Sulfur needs to lose six electrons to reach a full octet. Each potassium atom needs access to
seven electrons to achieve a full octet. Sulfur and potassium share six electrons, forming a
covalent bond.

C. Sulfur needs to lose six electrons to reach a full octet. Each potassium atom needs access to
seven electrons to achieve a full octet. One sulfur atom donates all its electrons to potassium,
forming an ionic bond.

D. Sulfur needs access to two electrons to reach a full octer Each potassium atom has one valence
electron that it prefers to lose to obtain a full octet. Therefore, two potassium atoms and one
sulfur atom complement each other and form an ionic bond,

Nanotechnology, the field of trying to build ultrasmall structures one atom at a time, has progressed in recent years. one potential application of nanotechnology is the construction of artificial cells. the simplest cells would probably mimic red blood cells, the body's oxygen transporters. for example, nanocontainers, perhaps constructed of carbon, could be pumped full of oxygen and injected into a person's bloodstream. if the person needed additional oxygen-due to a heart attack perhaps, or for the purpose of space travel-these containers could slowly release oxygen into the blood, allowing tissues that would otherwise die to remain alive. suppose that the nanocontainers were cubic and had an edge length of 24 nanometers. part a part complete what is the volume of one nanocontainer? (ignore the thickness of the nanocontainer's wall.) express your answer using two significant figures. v v = 1.4ă—10â’20 l previous answers correct significant figures feedback: your answer 1.3824â‹…10â’20 = 1.382ă—10â’20 l was either rounded differently or used a different number of significant figures than required for this part. if you need this result for any later calculation in this item, keep all the digits and round as the final step before submitting your answer. part b suppose that each nanocontainer could contain pure oxygen pressurized to a density of 81 g/l . how many grams of oxygen could be contained by each nanocontainer?

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
