I think you mean the nitrate ion. Yes, that is a polyatomic ion with a negative
charge. You write it as : NO3-
MgBr2 is ionic, and so would be considered polar.
I don't know because my chemistry teacher is greedy
The molecular formula is Co(NO3)2Co(NO3)2
Chromium (III) Nitrate
A fast way to answer it is that HNO3 is soluble in water and water is polar so HNO3 is polar Another explanation is that HNO3's H will form dipole hydrogen bonds with other molecules (IMF) thus is considered as polar

Copper nitrate, Cu(NO3)2, is a polar molecule. This is because the nitrate (NO3) ions have a negative charge due to the presence of the oxygen atoms, while the copper ion (Cu) has a positive charge. The difference in electronegativity between copper and nitrogen/oxygen atoms results in an uneven distribution of electrons, making the molecule polar.
NO3 is known as nitrate.
The molecular formula is Co(NO3)2Co(NO3)2
Iron nitrates are: - Fe(II)(NO3)2 - Fe(III)(NO3)3
The formula for the nitrate ion is NO3 -1.
Chromium (III) Nitrate
NI(NO3)3+pbbr4nibr3+pb(no3)4
NO3 is commonly known as nitrate.
Mg(NO3)2
