Was ist NH4+?

Bei Ammonium (NH4+) handelt es sich um eine für Fische und nahezu unschädliche Stickstoffverbindung. Im Meerwasseraquarium werden Stickstoffe hauptsächlich über das Futter und die damit verbundenen Ausscheidungen durch die Fische eingebracht.

How many sigma bonds does NH4+ have?

Most common types of hybridizations are sp, sp2, sp3, sp3d, sp3d2, sp3d3 etc. Ammonium ion formed by the release of an electron has 8 total electrons in the valence shell. In NH4+, nitrogen and the 4 hydrogen atoms make 4 sigma bonds, out of which 3 are covalent bonds and the fourth one is a dative bond. The NH4+ ion has no pi bonds.
