Front

Define ionic bonding.

Back

Ionic bonding is the electrostatic attraction between oppositely charged ions, typically formed when electrons are transferred from one atom to another.

Front

What is the significance of valence electrons in chemical bonding?

Back

Valence electrons are the outermost electrons of an atom and are involved in forming bonds with other atoms.

Front

How do metallic bonds differ from ionic bonds?

Back

Metallic bonds involve a 'sea of electrons' that are free to move, while ionic bonds involve the transfer of electrons and the attraction between charged ions.

Front

What is the typical charge of a nonmetal ion?

Back

Nonmetals typically gain electrons and form negative ions (anions), often with a charge of -1, -2, or -3.

Front

What happens to the electronegativity difference in a covalent bond?

Back

In a covalent bond, the electronegativity difference is usually less than 1.7, leading to shared electrons.
