Ionic, Covalent, Metallic

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically between a metal and a non-metal.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons, usually between non-metal atoms.

Front

What is a metallic bond?

Back

A metallic bond is a type of chemical bond that occurs between metal atoms, characterized by a 'sea of electrons' that are free to move around, allowing for conductivity and malleability.

Example of an ionic compound:

Back

Sodium chloride (NaCl) is an example of an ionic compound, formed from sodium ions (Na+) and chloride ions (Cl-).

Front

Example of a covalent compound:

Back

Sulfur dioxide (SO2) is an example of a covalent compound, formed by the sharing of electrons between sulfur and oxygen atoms.

Front

What are the properties of ionic compounds?

Back

Ionic compounds typically have high melting and boiling points, are soluble in water, and conduct electricity when dissolved in water.

Front

What are the properties of covalent compounds?

Back

Covalent compounds usually have lower melting and boiling points compared to ionic compounds, may not be soluble in water, and do not conduct electricity.

Front

What are the properties of metallic compounds?

Back

Metallic compounds are good conductors of heat and electricity, malleable, ductile, and have a shiny appearance.

Front

How do you identify an ionic compound?

Back

Ionic compounds are usually formed between metals and non-metals and often have a high difference in electronegativity between the two elements.

Front

How do you identify a covalent compound?

Back

Covalent compounds are typically formed between non-metals and have similar electronegativities, resulting in shared electrons.
