Ionic and Covalent Bonds

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

How can you identify an ionic compound?

Back

Ionic compounds typically consist of a metal and a non-metal, and they usually have high melting and boiling points.

Front

How can you identify a covalent compound?

Back

Covalent compounds usually consist of non-metals and have lower melting and boiling points compared to ionic compounds.

Front

What is the significance of valence electrons in bonding?

Back

Valence electrons are the outermost electrons of an atom and are involved in forming bonds with other atoms. Atoms tend to bond to achieve a full outer shell, usually 8 electrons.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons, leading to stability.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together, which can be either covalent or ionic.

Front

What is an example of an ionic compound?

Back

An example of an ionic compound is sodium chloride (NaCl), formed from sodium (Na) and chlorine (Cl) ions.

Front

What is an example of a covalent compound?

Back

An example of a covalent compound is water (H2O), formed from hydrogen and oxygen atoms sharing electrons.

Front

What happens to electrons in ionic bonding?

Back

In ionic bonding, electrons are transferred from one atom to another, resulting in the formation of positively and negatively charged ions.
