yes, diatomic and polyatomic ions can both be expressed in electron dot diagrams, or as your reffer to them; Lewis structures.
The polyatomic ion SO5 does not exist. The closest polyatomic ion to this is SO4^2- which is called sulfate ion.
The polyatomic ion OCN- is called cyanate.
There are three Lewis resonance structures for the SO3 2- ion. This is because sulfur can form multiple double bonds with the oxygen atoms, resulting in different arrangements of the double bonds and lone pairs.
To draw resonance structures for a polyatomic ion, start by determining the total number of valence electrons available, including those contributed by the ion's charge. Next, sketch a valid Lewis structure that satisfies the octet rule for the atoms, ensuring that the overall charge of the ion is correctly represented. Then, identify any possible shifts of electrons—typically lone pairs or double bonds—to create alternative structures while maintaining the same arrangement of atoms. Finally, ensure that each structure shares the same total number of electrons and charge, as they collectively represent the ion's resonance.
A polyatomic ion. For example, ammonium, chemical formula (NH4) with a 1+ electrical overall charge.
The -ite or -ate ending in a polyatomic ion is simply an indication of the amount of oxygen atoms present. The -are ending is used in the base form. If the polyatomic ion has one less oxygen atom than the -ate form, the -ite form applies.
The polyatomic ion oxide is O2-, which consists of two oxygen atoms with a charge of -1. This ion is commonly found in compounds such as magnesium oxide (MgO) and carbon dioxide (CO2). Oxoanions containing oxygen and other elements can also form polyatomic ions with the oxide ion.
The polyatomic ion is the ammonium ion, NH4^+
A polyatomic ion.
The polyatomic ion SO5 does not exist. The closest polyatomic ion to this is SO4^2- which is called sulfate ion.
The polyatomic ion for nitrite is NO2-.
The polyatomic ion is a carbonate ion, with formula CO3-2.
yes it is polyatomic ion because it is made up of more than 2 atoms
KOH is an ionic compound with a polyatomic ion. The hydroxide ion (OH-) is a polyatomic ion that is composed of one oxygen atom and one hydrogen atom.
The polyatomic ion is a carbonate ion, with formula CO3-2.
This is the ion acetate.
Na2Cr2O7 is an ionic compound with a polyatomic ion. The polyatomic ion present in this compound is the chromate ion (Cr2O7)^2-.
