Molecules that have the same chemical formula (same numbers of each atom) but different three-dimensional shapes are called ____

Sveta_85 [38]

Answer:

Molecules that have the same chemical formula (same numbers of each atom) but different three-dimensional shapes are called Stereoisomers.

Explanation:

Stereoisomerism is a phenomenon in which molecules have same molecular formula but have different arrangement of atoms or group of atoms in space. It is further classified as;

i) Geometrical Isomerism:

In this class of isomerism the groups or atoms about the double bond occupies different region in space. It is also called as cis-trans isomerism.

ii) Optical Isomerism:

In this class the molecules having same molecular formula differ in their interaction towards plane polarized light.

Which of these statements best describes the formula unit for a compound made from Mg and Cl?

olga2289 [7]

Answer:

It is MgCl₂ because the total positive charge on Mg is two

Explanation:

The bond between the atoms that makes up the formula unit of the compound is an ionic bond. This bond involves the transfer of electrons between atoms.

Mg is in the second group on the period on the periodic table. It has two valence electrons and would readily lose it to have a stable atomic configuration like those of noble gases. This leaves magnesium with a net positive charge of 2. Each chlorine atom gains one electron to achieve their own octet.
