The NH4 asked about is the amonium ion, and it's written NH4+ to indicate it has a positive charge (+1). It's a cation. Wikipedia has more information on this chemically significant polyatomic ion, and you'll find that a link to that post is provided below.
Uranium
This oxide is called dinitrogen pentoxide.
(NH4)+ is a cation (ammonium).
In chemistry, "K" can also stand for the equilibrium constant, which is a measure of the ratio of the concentrations of the products to the concentrations of the reactants at equilibrium in a chemical reaction.
They are used to fix an object to a bar from a stand.
No, the formula SO4 2- stands for the sulfate ion, not ammonium. Ammonium is represented by the formula NH4+.
NH3 is classified as a base in chemistry because it can accept a proton (H) from an acid to form the ammonium ion (NH4), making it capable of neutralizing acids.
In chemistry, "UG" stands for "Uranium Glass."
I think this belongs in Chemistry NH3 is Ammonia and NH4 would be an ammonia ION which is called Ammonium
carbon
Uranium
Sulfur
francium
it's very complicated go ask your chemistry teacher. actually i don't know
"NH4" I assume is NH4+This is the ammonium ion.
In Chemistry it stands for Iron
The letter U stands for Uranium.
