Sanna and Eddie are getting breakfast at a coffee shop. Sanna bought a chocolate donut, and Eddie bought an apple fritter. Both Sanna and Eddie want to try the other person’s donut. Metaphorically speaking, if donuts were valence electrons, describe in terms of non-polar covalent, polar covalent, and ionic interactions how the donuts will be shared between Sanna and Eddie. Draw pictures in your notebook so that you can visualize what you’re describing. Remember to mention which type of interaction you are referring to for each scenario: non-polar covalent, polar covalent, and ionic.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
