NH4 WILL HAVE 1 LONE ELECTRON AS 4 GOT INCLUDING IN BONDING BUT IT CAN BE INSTEAD NH4+ THUS THE LONE ELECTRON HAS BEEN LOST THUS NH4+ HAS 4 bond pairs and no lone pairs
2
NH4+ is isoelectronic with CH4. The bonding is similar- 4 electron pairs. these are not delocalised.
The molecular geometry of NH4+ is tetrahedral. This is because NH4+ has four bonding regions (four hydrogen atoms bonding with the central nitrogen atom) and no lone pairs of electrons on the central nitrogen atom.
In order to have a net charge of zero, nitrogen can have three bonds. it will often have more or less than that number with a charge on the atom. Example: Ammonia (NH3) versus Ammonium (NH4+)
the bond in NH4Cl is somewhat ionic because NH4 is positive and CL is negative
NH3 is a bronsted base. It has a lone pair.
These species are both polyatomic ions. NH4 + (ammonium ) and SO4 2- ( sulfate ) combine with opposite charges to form (NH4)2SO4 which is ammonium sulfate a polyatomic ionic bonding.
NH4+ is an ammonium ion while Cl- is simply a chloride ion. Reactions between ions are known as ionic bonding. Thus, the answer to your question is ionic bond. When reacted together, the following equation happens: NH4 + Cl --> NH4Cl
Due to the VSEPR theory (the valence shell electron pair repulsion theory) It has a tetrahedral shape because it has four negative charge centres. When there are four negative charge centres and all there are four bonding pairs of electrons the shape is tetrahedral. for future reference any atom with 4 negative charge centres will have the following structures (depending on how many of the electron pairs (negative charge centres) are bonded): all bonding pairs: tetrahedral (for example ccl4, ch4 nh4 bf4) 3 bonding and 1 non bonding: trigonal pyramid (e.g. ammonia) 2 bonding and 2 non bonding: bent (v-shaped) - for example water.
H2O, as the difference in electronegativity between hydrogen and oxygen is the largest (among the options given: SO3 , SO3-- , NH4+, H2O)
NH3 is eventually covalent because they are sharing electrons.
the ion NH4+ has five atoms (one nitrogen and four hydrogen)
