The electron pairs in an ammonium ion are disposed along the four lines from the center of a tetrahedron to the four corners of the tetrahedron, with the nitrogen atom at the center of the tetrahedron.
The ammonium ion is (NH4)+.
Ammonium ion has a single positive charge. + ie NH4
Ammonium ion (NH4+) is present in all ammonium salts (eg. ammonium chloride, or ammonium nitrate), and in smaller amounts in an ammonia (NH3) solution.
It is considered an Ionic bond. Ammonium donates an electron and nitrate accepts an electron. By itself, ammonium ion is a molecular compound and the nitrate ion is a molecular compound, but when combined they are considered to be ionic. Only molecular compounds can be covalent bonded and are designated: covalent, polar, or nonpolar. The difference between polar and nonpolar depends on the difference of electronegativities of the atoms present.
Ammonium ion is polar due to the ionic bonds present in the polyatomic ion.

carbonate ion is having trigonal planar geometry
The molecular geometry of the AsO2- ion is bent (because of the lone electron pair with the central arsenic atom, making the O-As-O bond angle very obtuse) but its electron domain geometry is trigonal planar because there are three domains, with a 120 deg. angle between them.
Its actually electron pair repulsion. Its the principle that electron pairs around a central atom tend to orient themselves as far apart as possible. Electron pair repulsion is used to predict the geometry of a molecule or a polyatomic ion.
sp2, trigonal planar, bent
Think of the sulfite ion as a molecule with its geometry and dipole moment AND a net charge. The electron pair geometry is tetrahedral and the molecular geometry is trigonal pyramidal and because of its asymmetrical shape and polar bonds, sulfite has a net dipole moment (2.04D ). The ion is polar.
ICl4-'s electron domain geometry is octahedral.
A Lewis acid accepts an electron pair.
it shows tetrahedral geometry for the electron pairs geometry and trigonal pyramid the molecular geometry.
None of them. A Lewis acid is a species which is an electron pair acceptor.
NH4+ ion is ammonium ion
The ammonium ion is (NH4)+.
