What is chemical name for Na2Cr2O2?
I am not familiar with Na2Cr2O2 although the web is crawling with that entry. It is sometimes referred to as Cr2O2-7 and called dichromate or romate but that is a crazy way of writing it. If you can provide more information I might be able to straighten things out. Frankly, I think it's fictitious.
Dichromate is Cr2O7 so
The chemical name for Na2Cr2O2 is sodium chromate.
The chemical name for Na2Cr2O2 is sodium chromate.
To determine the chemical name, we need to understand the formula of the compound. In this case, the formula is Na2Cr2O2.
The chemical name is made up of the names of the elements present in the compound. In this case, we have sodium (Na), chromium (Cr), and oxygen (O).
To determine the name for each element, we use the periodic table. Sodium is located in Group 1, so its name is simply "sodium." Chromium is located in Group 6, so its name is "chromium." Oxygen is located in Group 16, so its name is "oxygen."
Now that we have the names for the individual elements, we put them together to form the chemical name. Since there are two sodium atoms in the compound, we use the prefix "di-," resulting in "sodium." The formula indicates that there are two chromium atoms, so we use the prefix "di-" again, resulting in "chromate." Finally, we add the suffix "-ate" to indicate that the compound contains oxygen.
Thus, the chemical name for Na2Cr2O2 is sodium chromate.
