Which statements show how a chemical bond is formed?
(Select all that apply.)
a. The valance electrons of an atom are emitted from an atom’s orbital.
b. The valence electrons of a metal transfer to the valence shell of a nonmetal to stabilize both atoms.
c. The valence electrons of metallic atoms are shared between all the positive ions.
d. The valance electrons of two or more nonmetals are shared to stabilize the atoms.
i think it is c and d
B and C are correct
thank you!
I think b eg NaCl, ionic bond Na gives electron to Cl
and d, covalent bond

To determine which statements show how a chemical bond is formed, we can analyze each option:
a. The valance electrons of an atom are emitted from an atom’s orbital.
This statement is incorrect. Electrons are not emitted from an atom's orbital during bond formation.
b. The valence electrons of a metal transfer to the valence shell of a nonmetal to stabilize both atoms.
This statement explains the formation of an ionic bond, where one atom donates electrons to another atom. However, it does not cover all types of chemical bonds.
c. The valence electrons of metallic atoms are shared between all the positive ions.
This statement refers to metallic bonding, where valence electrons are delocalized and shared among all the metal atoms. This type of bonding is specific to metals.
d. The valance electrons of two or more nonmetals are shared to stabilize the atoms.
This statement correctly describes covalent bonding, where valence electrons are shared between two or more nonmetal atoms. Covalent bonds are formed when atoms share electrons to achieve a stable electron configuration.
Based on the explanations above, the correct statements that show how a chemical bond is formed are:
- c. The valence electrons of metallic atoms are shared between all the positive ions. (for metallic bonding)
- d. The valance electrons of two or more nonmetals are shared to stabilize the atoms. (for covalent bonding)
Therefore, you are correct in selecting options c and d as the statements that show how a chemical bond is formed.
