Bonding Ionic/Covalent

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, typically between nonmetals.

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, usually between a metal and a nonmetal.

Front

What are ionic compounds?

Back

Ionic compounds are substances formed from the electrostatic attraction between cations (positively charged ions) and anions (negatively charged ions). They typically have high melting and boiling points.

Front

What are covalent compounds?

Back

Covalent compounds are substances formed when two or more nonmetals share electrons. They usually have lower melting and boiling points compared to ionic compounds.

Front

Which group of elements typically forms covalent bonds?

Back

Nonmetals, particularly those in Groups 14, 15, and 16 of the periodic table, typically form covalent bonds.

Front

Which group of elements typically forms ionic bonds?

Back

Metals, particularly those in Groups 1 and 2 of the periodic table, typically form ionic bonds with nonmetals.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is a cation?

Back

A cation is a positively charged ion that is formed when an atom loses one or more electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion that is formed when an atom gains one or more electrons.

Front

What is the difference between a polar and nonpolar covalent bond?

Back

A polar covalent bond occurs when electrons are shared unequally between atoms, resulting in partial charges. A nonpolar covalent bond occurs when electrons are shared equally.
