Answer:
1. How many electrons does hydrogen need in order to have a full shell of valence electrons?...two
2. How do valence electrons impact the type of bonds an atom makes?...An atom wants a full outer shell of valence electrons, so it will either transfer or share electrons depending on what the other atom needs.
3.Use your knowledge of valence electrons and how they affect bonds to figure out how carbon (Group 14) and oxygen (Group 16) would be attached to one another. In carbon dioxide (CO2), how is the compound structured? (Use “–” to represent a single bond and “=” to represent a double bond.)...O=C=O
4. Methane’s chemical formula is CH4. Is there a bond between any of the hydrogen atoms? Why or why not?...No, there is not because carbon needs four bonds, so it bonds with each hydrogen atom; hydrogen only forms one bond.
5. In hydrogen peroxide (H2O2), which option best shows how the atoms are ordered?...H-O-O-H
Explanation:
The Lewis structure of the hydrogen cyanide molecule is represented by the image shown.
<h3>
What is the Lewis structure?</h3>
We know that the Lewis structure is showing us the relationship between the electrons pairs in the compound and its overall properties. The Lewis structure consists of the symbol of the element and the electrons pairs that surround the atom.
We can see that in hydrogen cyanide there is a nitrogen atom and there is a hydrogn atom and also one carbon atom. The bond between carbon and nitrogen is covalent while the bond between hydrogen and the cyanide moiety is covalent.

The answer to this question would most definitely be the last one
The enthalpy of fusion of a substance is the energy required to change the state of a substance from solid to liquid at a constant temperature. The enthalpy of fusion for iodine, I₂, will be higher. This is because there are stronger intermolecular forces holding the iodine molecules together. The stronger intermolecular forces arise from the fact that iodine is a much larger molecule, so it has much more electrons resulting in higher Van der Waal's forces. This is also visible in the fact that at room temperature, iodine is a solid while nitrogen is a gas.<span />
