Modeling Molecules

1-1: Insert the chemical symbol in the answer blank for each of the following elements.

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.

5. Write a structural diagram equation to represent the controlled oxidation of each alcohol in

Formulas for compounds can be written as empirical or molecular formulas where empirical formulas are the simplest formula of a compound and a molecular formula is the actual, or true, formula of a compound. These are the same form in ionic compounds, but may differ in covalent. For example, in Benzene, a covalent

2. Using the atom and bond library below, construct the following molecule. It may be

What is the molecular geometry around a central atom that is sp2 hybridized, has three sigma bonds, and one pi bond?

A) They feature carbon atoms which are covalently bonded to hydrogen (Open Learning Initiative, 2015, pg.63).

33. Electron dot model is a way of representing the valence electron of an atom.

Draw correct Lewis structures to model covalently bonded molecules when given the name or formula of the molecule.

Sketch the electron dot structure for the following elements (ask about the easy way to find the valence electrons):

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.

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

Essential knowledge 4.A.1: The subcomponents of biological molecules and their sequence determine the properties of that molecule

2. Ozonolysis of compound Z yields the products shown below. What is the structure of Z?
