Flashcards

Ions

Atoms that have gained or lost electrons, giving them a positive or negative charge.

Cations

Positively charged ions formed when an atom loses electrons.

Anions

Negatively charged ions formed when an atom gains electrons.

Ionic Bonding

The electrostatic attraction between oppositely charged ions, formed when one atom gives up electrons and another atom gains them.

Study Notes

Ions

Ions are charged particles.
Ions are categorized into cations (positive charge) and anions (negative charge).

Ionic Bonding

Ionic bonds form when there is a complete transfer of electrons between a metal and a nonmetal.
This transfer results in both atoms attaining a full valence electron shell.
The metal loses electrons, becoming a cation.
The nonmetal gains electrons, becoming an anion.
The opposite charges of the cation and anion attract each other, forming an ionic bond.

Covalent Bonding

Covalent bonds form when two nonmetals share electrons.
This sharing of electrons allows both atoms to achieve a full valence shell.

Water (H₂O)

Water (H₂O) is a molecule that requires two additional electrons to complete its outer electron shell.
