The answer is (1) HI. H and I are both nonmetals, and remember that a molecular compound is one in which covalent bonds hold atoms together, and covalent bonds typically form between nonmetals. The other three choices represent ionic compounds (metal and nonmetal).

g Stereoisomers that are not mirror images of each are ____________ . The cis and trans isomers of a particular compound are ___
mel-nik [20]

Answer:

Diasteriomers

Stereoisomers

Stereoisomers

Meso compounds

Constitutional isomers

Enantiomers

Enantiomers

Explanation:

Isomers are compounds that posses the same molecular formula but different structural formulas.

Constitutional isomers differ only in atom to atom connectivity while stereoisomers differ in arrangement of atoms in space. Stereo isomers differ in physical and chemical properties of the compounds.

When stereo isomers are non-superimpossible mirror images of each other, they are called enantiomers. Enantiomers have the same chemical and physical properties and differ only in their reaction with chiral substances.

Achiral compounds are compounds that do not exhibit chirality. Some achiral compounds contain stereogenic centers and are called meso compounds.

Explanation:

The atom having only one electron its outermost shell must belong to an element in group one of the periodic table.

Having noted that, we proceed to find out what element in group one that has the atom just described in the question.

That atom must belong to an element in the fourth period. The only group 1 element in the fourth period is potassium.

The electron configuration of potassium is;
