Homework for Monday: Naming Practice worksheet
Quiz Monday- Covalent Naming
On Thursday and Friday, we began to study two types of bonds between atoms, ionic and covalent bonds.
Ionic bonds
On Thursday we began learning about ionic bonds. An ionic bond is a bond formed between one positive and one negative atom. We began with a worksheet that helped us better understand what an ionic bond was. For example, we had to list any similarities that we noticed between several examples. These similarities included that the first element in an ionic bond was a metal, and that the second element was a non-metal that ended with the suffix -ide. Below is an example of how an ionic bond is formed.
Ionic bond:
On Friday, we started class with a short quiz on ionic bonds. After the quiz, we started a worksheet, similar to the one about ionic bonds, that introduced us to covalent bonds.
Covalent bonds
On Friday after the quiz, we began to learn about covalent bonds. As mentioned above, we started a worksheet that introduced us to covalent bonds. A covalent bond is a bond formed between two atoms that share electrons. We identified patterns that we noticed between examples given on the worksheet. Some similarities were that the second element ended with -ide, both elements used Greek prefixes, and the first element is a non-metal.
Covalent bond:
We also began learning how to name and identify the two types of bonds. Some examples for naming ionic bonds are:
Copper (I) Chloride ---> Cu2Cl
and Iron (III) oxide ---> Fe2O3
Covalent bonds use Greek prefixes for naming compounds. Some examples for naming covalent bonds are:
NO2 ---> Nitrogen dioxide
CO ---> Carbon monoxide If you noticed, in this example a prefix for carbon was not added, because as a rule prefixes . are only added to the first atom in a covalent bond if there is more than one. For example:
P2O5 is diphosphorus pentoxide
The quiz monday will cover covalent bonds and covalent naming, as explained above.
The next scribe will be Johnny O.
