That would be chromium(IV) selenide with the formula CrSe2
The manganese(IV) selenide has the chemical formula MnSe2.
Sodium selenide is a compound formed between sodium and selenium.
Chromium(III) borate has the chemical formula CrBO3.
The answer from my chem class states its Cr(NO3)2
Because in a chemical compound is a chemical bond between the elements. From a mixture of iron and sulfur iron can be separated with a magnet.
FeSe
The manganese(IV) selenide has the chemical formula MnSe2.
Sodium selenide is a compound formed between sodium and selenium.
The compound formed between sodium and selenium is named "sodium selenide" and has the formula Na2Se.
Chromium(III) borate has the chemical formula CrBO3.
The formula would be K2Se
an Ionic compound
The answer from my chem class states its Cr(NO3)2
It is ionic compound as the difference in the electronegativity between chromium and oxygen is more than 1.7
Chromium (II) chloride = CrCl2Chromium (III) chloride = CrCl3 Chromium (IV) chloride = CrCl4
Type of bonding between elements in a compound chemical-chemically is chemical bonding.
the difference is that the formula does not have the same categories as the chemical compound does
