Ionic/covalent/metallic 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 formed when one atom donates an electron to another.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond formed when two atoms share one or more pairs of electrons.

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.

Front

How do you determine the type of bond between two elements?

Back

The type of bond can be determined by the difference in electronegativity between the two elements: ionic bonds form between metals and nonmetals, covalent bonds form between nonmetals, and metallic bonds occur between metals.

Front

What are valence electrons?

Back

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

Front

How many valence electrons does an element in Group 1 have?

Back

Elements in Group 1 have 1 valence electron.

Front

How many valence electrons does an element in Group 17 have?

Back

Elements in Group 17 have 7 valence electrons.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons in order to have a full outer shell of 8 electrons, achieving stability.

Front

What happens to the electrons in an ionic bond?

Back

In an ionic bond, one atom donates electrons to another atom, resulting in the formation of positively and negatively charged ions.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds occur when electrons are shared unequally between atoms, while nonpolar covalent bonds occur when electrons are shared equally.
