Arsenic is a chemical element.
Hydrogen iodide is a covalent compound.
PtO2 is a molecular compound because it is composed of nonmetal atoms (oxygen) bonding with a transition metal atom (platinum) through covalent bonds. It does not consist of ions held together by ionic bonds.
Molecular compounds are formed by sharing of electrons between atoms, resulting in covalent bonds, while ionic compounds are formed by transferring electrons from one atom to another, resulting in ionic bonds. Molecular compounds have discrete molecules with defined molecular formulas, while ionic compounds do not have discrete molecules and are represented by empirical formulas showing the ratio of ions present in the compound.
Ammonia is a molecular compound. The hydrogen atoms share electrons with the nitrogen atom.
Ni3 is ionic because it consists of a metal (Ni, nickel) and non-metal atoms (3 atoms of the same element), indicating the transfer of electrons from the nickel atom to the non-metal atom to form ions.
If a compound contains at least one metal atom and at least one nonmetal atom, the compound is ionic. Na (Sodium) is a metal. Br (Bromine) is a nonmetal. Therefore, the compound NaBr is ionic.
Hydrogen iodide is a covalent compound.
Any compound, whether molecular or ionic, will contain two or more types of atom.
PtO2 is a molecular compound because it is composed of nonmetal atoms (oxygen) bonding with a transition metal atom (platinum) through covalent bonds. It does not consist of ions held together by ionic bonds.
Since Lithium is an alkaline earth, it is expected to form ionic bonds. An ionic bond with Hydrogen will result with each atom having a full 1s shell.
