Ionic Bond and Chemical Bonds

These flashcards cover key concepts related to ionic bonds, types of chemical bonds, properties of ionic compounds, and common ions.

Ionic Bond

A type of chemical bond formed through the transfer of electrons from a metal to a non-metal, resulting in the attraction between oppositely charged ions.

Cations

Positively charged ions formed when an atom loses one or more electrons.

Anions

Negatively charged ions formed when an atom gains one or more electrons.

Octet Rule

Atoms achieve stability by having eight electrons in their outermost shell.

Electrostatic Forces

The forces of attraction between oppositely charged ions that hold them together in an ionic bond.

Noble gases

Elements in Group 18 of the periodic table that have a full valence shell, making them stable and unreactive.

Ionic Compounds

Compounds formed from the electrostatic attraction between cations and anions.

Properties of Ionic Compounds

Typically hard, with high melting points and the ability to conduct electricity when molten or in solution.

Metallic Bond

A type of chemical bond where metal atoms share electrons in a 'sea of electrons', allowing for conductivity and ductility.

Covalent Bond

A type of chemical bond formed when non-metal atoms share pairs of electrons.

Hydroxide Ion

A negatively charged polyatomic ion made of oxygen and hydrogen, denoted as OH-.

Sulfate Ion

A negatively charged ion composed of sulfur and oxygen atoms, denoted as SO4^2-.

Formation of Ionic Compounds

Occurs when electrons are transferred from a metal to a non-metal, resulting in the formation of cations and anions.

Dichromate Ion

A polyatomic ion composed of chromium and oxygen, denoted as Cr2O7^2-.

Permanganate Ion

A polyatomic ion that contains manganese and oxygen, denoted as MnO4^-.
