Argon is chemically inert due to the presence of completely filled orbitals. It does not react with other elements and hence does not form ionic or covalent compounds at STP.
Covalent molecules with small amounts of argon which is monatomic. All molecules are covalent. Ionic compounds form crystals, not molecules.
Compounds with covalent bonds form molecules. Compounds with ionic bonds form ionic lattices.
Sulfur can form both ionic and covalent compounds. For example, sulfur dioxide is a covalent compound whereas sulfides of metals are ionic compounds.
Generally covalent compounds.
ionic and covalent compound
"Shares electrons" is a characteristic of covalent bonds, which form covalent compounds.
Ionic compounds
It is neither. Argon, being a NOBLE/Inert gas, does NOT form any compounds, be they ionic or covalent. As a Noble Gas it is described as Monatomic. It exists as SINGLE unreactive atoms.
Chlorine, Cl2 is covalent. Any molecules which consist of two atoms of the same element must be covalent. In compounds with other elements chlorine can form ionic or covalent compounds.
Calcium fluoride is an example of an ionic compound, not a covalent compound. Covalent compounds form between two nonmetals, while ionic compounds form between a metal and a nonmetal.
No. Ionic compounds are formed by transfer of electrons Covalent compounds are formed by sharing of electrons
ammonium compounds are ionic compounds but with in ammonium ion three hydrogens form covalent bonds while 4th forms coordinate covalent bond.
