Ionic and Covalent Bonding

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

Which types of elements typically form ionic compounds?

Back

Ionic compounds are typically formed between metals and non-metals.

Front

What charge do metals typically have in ionic compounds?

Back

Metals typically lose electrons and have a positive charge in ionic compounds.

Front

What charge do non-metals typically have in ionic compounds?

Back

Non-metals typically gain electrons and have a negative charge in ionic compounds.

What is the formula for magnesium oxide?

Back

The formula for magnesium oxide is MgO.

Front

What is the correct name for the compound NaCl?

Back

The correct name for NaCl is sodium chloride.

Front

What is the difference between ionic and covalent compounds in terms of conductivity?

Back

Ionic compounds conduct electricity when dissolved in water or melted, while covalent compounds generally do not conduct electricity.

Front

What is the significance of the octet rule in bonding?

Back

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