could be monatomic but many ions are comprised of multiple atoms - for example when sulfuric acid dissociates, one of the ions it yields is SO4-- (having trouble getting a superscript but the ion has a double negative charge)
Sodium ionSodium, Na, becomes a single positive cation Na+
The ion SO32- is called sulfite ion. It is composed of one sulfur atom and three oxygen atoms, with a charge of -2.
A monoatomic ion has only one atom examples are chloride, Cl-, fluoride, F-, sodium Na+ A polyatomic ion has more than one, e.g sulfate SO42-, nitrate, NO3-, mercurous, Hg22+ Poly is from the Greek and means "many"
The most common ion formed from a single sulfur atom is a sulfide ion, with a charge of -2.
A hydroxide molecule has one bond between the oxygen and hydrogen atoms. The hydrogen atom donates its electron to form a bond with the oxygen atom, resulting in a covalent bond between the two atoms.
no
No. The bromide ion (Br-) contains only a single atom of bromine with an extra electron.
No, the chloride ion is a single elemental ion, Cl-.
A charged ion that is composed of two or more atoms covalently bonded.No: Each chloride ion contains only one atom.
No. S2- is a monatomic ion. A polyatomic ion contains at least two atoms. You can identify a polyatomic ion as it will have the symbols for more than one element (OH-), a subscripted number (O22-), or a combination of the two (CO32-). The superscript in the ion only indicates the charge.
Sodium ionSodium, Na, becomes a single positive cation Na+
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.
molecular ions
Ions that consist of a single atom are called monatomic ions
Peroxide is considered a polyatomic ion because it is composed of more than one atom covalently bonded together. It has a unique structure and charge as a whole that cannot be explained by a single atom gaining or losing electrons. Simple ions are single atoms that have gained or lost electrons to obtain a full outer electron shell.
An ion is a single atom that carries a positive or negative charge due to gaining or losing valence electrons. The atom becomes an ion when it has an unequal number of protons and electrons.
The ion NH4+ is the ammonium ion. It is a positively charged polyatomic ion composed of one nitrogen atom and four hydrogen atoms.
