The halides are a family.
Barium is a metal that typically forms a +2 cation (Ba^2+). Monoatomic anions are negatively charged ions formed from a single atom. Barium can form various monoatomic anions, such as oxide (O^2-), chloride (Cl^-), and sulfide (S^2-).
Cations are positive ions (Fe2+, NH4+).Anions are negative ions (Cl-, (SO4)2-).Fe2+ is a monoatomic ion and (NH4)+ is a polyatomic Ion (contain more than one element).
Monatomic anions are formed when atoms gain one or more electrons. The number of protons in the nucleus remains the same, giving the atom a net negative charge due to having more electrons than protons.
Copper is a monoatomic chemical element.
Hydronium is a polyatomic cation.
No, sodium is an element that exists as single atoms and not as molecules. Sodium is a monoatomic element because it consists of single atoms.
Argon is a monoatomic gas, meaning it exists as individual atoms in its natural state.
No, its monoatomic
Helium is monoatomic.
Yes
yes they exsist as monoatomic molecule in vapour state
Helium is monoatomic.
