NH4+, or ammonium, has a tetrahedral shape with a covalent bond angle of 109.5 degrees between the hydrogen atoms. The bond length of the nitrogen-hydrogen bond is about 1.04 Angstroms.
The name for the IO4--ion is 'per-iodate'- or 'periodate'-ion (pronounce with 4 syllables: per-i-o-date)
A chloride ion. ( Cl- ) and any other ion form of the elements in group 7 of the Periodic Table (7th from the left, 2nd from the right) or an Electron. A variety of polyatomic ions have -1 charges including the nitrate ion (NO3-), hydroxide ion (OH-) and perchlorate ion (ClO4-)
molecular ions
Ammonium perhclorate is a salt. It is weakly acidic due to the presence of the ammonium ion.
The silver ion is Ag+ and the perchlorate ion is ClO4-, so silver perchlorate would have the formula of AgClO4.
The OsbCl3 ion has a tetrahedral molecular shape
the ammoniun ion has a tetrahedral molecular shape. It has four groups of electrons surrounding the nitrogen atom. The fact that the ion has an overall charge does not affect the shape.
ClO4- is the perchlorate ion.
trigonal planar
The perchlorate ion has one available bond.
The electronic shape is trigonal planar.The molecular shape is bent/angular.
Ammonium Perchlorlate - NH4ClO4 The negative perchlorate ion (NH4+) is ionically attracted to the positive ammonium ion (ClO4-).
The ion nitrate has a trigonal planar structure; see the link below.
IO^- is named as hypoiodite anion. It is unstable and disproportionates to I^- & IO^3-
No ClO4 (or more properly ClO4-) is an ion, known as the perchlorate ion. It does not exist on its own, bur is accompanied by a positive ion. It can exist as a part of a solid in pure perchlorate salts, or in water as dissolved perchlorate salts or perchloric acid.
It is actually ClO4- which is Perchlorate ion
