How do you write the name of a compound made of 2 nonmetals
When writing the name of a compound made of two nonmetals, you usually use the following rules:
1. The element occurring first in the formula is named first.
2. The second element's name is modified by changing its ending to "-ide."
3. You may need to use prefixes to indicate the number of atoms for each element, except when the first element only has one atom.
Here's an example:
Compound: CO2
The element "C" (carbon) occurs first, so it is named first. The second element "O" (oxygen) is modified by changing its ending to "-ide."
Name: Carbon Dioxide
To write the name of a compound made of two nonmetals, you can follow these steps:
1. Identify the nonmetal elements present in the compound.
2. Determine the number of atoms of each element in the compound using the subscripts.
3. Write the name of the element that appears first in the compound formula.
4. Write the name of the second element, but change the ending to "-ide."
5. If there is more than one atom of each element present, use the prefixes to indicate the number of atoms.
Here's an example to illustrate these steps:
Compound: CO₂
1. The nonmetal elements present are carbon (C) and oxygen (O).
2. There is one carbon atom and two oxygen atoms in the compound.
3. Carbon appears first, so we write "carbon."
4. Oxygen is the second element, and we change the ending to "-ide." Therefore, it becomes "oxide."
5. Since there is only one carbon atom, we don't need to use a prefix for carbon. However, since there are two oxygen atoms, we use the prefix "di-" to indicate this. Therefore, the name of the compound is "carbon dioxide."
Remember, if there are no prefixes, it means there's only one atom of each element in the compound.
To write the name of a compound made of two nonmetals, you need to follow a specific naming convention. Here's a step-by-step guide:
1. Identify the elements in the compound.
For example, let's consider the compound Carbon (C) and Oxygen (O).
2. Determine the number of each element in the compound using subscripts.
In this case, let's consider carbon dioxide, which contains one carbon atom and two oxygen atoms. The formula for carbon dioxide is CO2.
3. Write the name of the first element.
In this example, carbon is the first element. The name of the first element remains the same.
4. Write the name of the second element.
Oxygen is the second element. Change the ending of the second element's name to "-ide."
5. Combine the names of the two elements.
In this case, carbon dioxide is the resulting compound.
So, the name of the compound made up of carbon and oxygen is "carbon dioxide." Remember to change the second element's name to end with "-ide" when writing the name of the compound.
