42. Ionic Bonds - Using a chemical diagram of your choice (ex. Electron dot diagram), for each of the following pair of elements: a) Show the transfer electrons, b) write the charge for each ion, and c) write the chemical formula for each. Potassium + Iodine

Magnesium + Oxygen

Lithium + Nitrogen

43. Covalent Bonds - For the following Pair of atoms: 1) Draw the structure of each atom (showing the number of electrons), 2) Use a circle to indicate which electrons are being shared, and 3) Write the bond structure and chemical formula

Fluorine + Fluorine

3 Hydrogen + 1 Phosphorus

2 Hydrogen +1 Sulfur

Why are gamma rays not affected by a magnet as they pass over it? gamma rays are composed of only energy. gamma rays do not have enough mass to be affected. gamma rays do not have the right electrical charge to be affected. gamma rays move too fast for anything to affect their pathway.

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?
