Modeling Molecules
Introduction:
You can represent a molecule two-dimensionally, as a structural formula or electron dot structure. Although such models are useful in certain contexts, they do not accurately represent bond angles between atoms or shapes of molecules. In this activity, you will construct three-dimensional models of several molecules. You will use electron dot structures and structural formulas to inform how you construct the three-dimensional models.
Materials:
Google
Microsoft Word
Paint (the computer tool)
Procedure:
1. Identify the chemical and structural formulas and electron dot structures of the following molecules:
water, ammonia, carbon dioxide,

Why?
It would make the most sense to use the electron dot structure. This one should be used because it shows the number of electrons that fluorine has, it also shows that fluorine has an unpaired electron. I know that fluorine has 7 valence electrons. Fluorine really wants to gain one more electron to become a noble gas, which means that it is willing to do just about anything to achieve that. That is why fluorine is so reactive; it will react with a lot of
Sketch the electron dot structure for the following elements (ask about the easy way to find the valence electrons):
7. The more-electronegative element in a binary compound is assigned the number equal to the charge it would have if it were an ion.
I can use these three values to characterize the structure, charge, and the mass of an atom by using the knowledge I know already. In the problem this atom has 3 protons so its atomic number will be 3 and its mass number equal the number of protons plus number of neutrons equal which you can write like this 3 + 4. The problem 3 + 4 will equal 7. This atom also has 3 electrons, balancing the charge of 3 protons that exist in its nucleus, concluding that this atom has an atomic number of 3 and a mass number 7. The element is
2. Using the atom and bond library below, construct the following molecule. It may be
A) They feature carbon atoms which are covalently bonded to hydrogen (Open Learning Initiative, 2015, pg.63).
What is the molecular geometry around a central atom that is sp2 hybridized, has three sigma bonds, and one pi bond?
1-1: Insert the chemical symbol in the answer blank for each of the following elements.
Draw correct Lewis structures to model covalently bonded molecules when given the name or formula of the molecule.
Essential knowledge 4.A.1: The subcomponents of biological molecules and their sequence determine the properties of that molecule
5. Write a structural diagram equation to represent the controlled oxidation of each alcohol in
Yes, I do believe as Americans, we should organize for reproductive justice rather than just settling on abortion rights, birth control and reproductive rights. The reason I believe we should just settle for reproductive justice because, it’s helpful for women who have suffered greatly. It is dangerous for us if we don’t let women think for themselves. For example, women who don’t receive a good quality of education will never be able to have a bright future for themselves and their children.
The students created a macroscopic, three-dimensional (3D) model of several properties of the periodic table. They explained in their own words the following terms: atomic radii, ionic radii, first ionization energy, and electronegativity. Lastly, they identified, described, and explained the patterns observed in the 3D periodic tables for the following element properties: atomic radii, ionic radii, first ionization energy, and electronegativity.
According to world recognized American Scientist Carl Sagan “the illegality of cannabis is outrageous, an impediment to full utilization of a drug which helps produce the serenity and insights , sensitivity and fellowship so desperately needed in this increasingly mad and dangerous world”. These are just some of the benefits of Marijuana along with many others. All you have been taught about cannabis in your lifetime is the negatives but it is important to consider facts about the benefits if you would like to form your own opinion. The heavily scrutinized legalization of cannabis would have many benefits including an estimated 28
Life as we know it is far more complex than one can imagine. The smallest molecule in the human body can play a large role in determining the genetic outcome or the overall well being of a person. In Peter Nielsen’s “Designing a New Molecule of Life”, he speaks of a molecule that hopefully one day will create a scientific and medical breakthrough. In this essay you will read a summary of Peter Nielsen’s article and the research he has done with this molecule.
In a society where an elite elegance has gotten rid of tools that the rulers do not allow because an this elite institution of people often use this gear to dominate and oppress society. In George Orwell’s story, Animal Farm, Orwell demonstrates that education is a powerful weapon and is a device that can be used to at least one’s benefit. Living in a world where strength is a straightforward to benefit, the pigs quick use education to govern the relaxation of the animals on the farm to serve themselves worked to their advantage. This story in shows the underlying message that first, training is important to all tiers of society, subsequent, for when it is not, society is stratified, ensuing in the masses struggling.
