Chemical Bonding

Front

What type of bond is formed between magnesium (Mg) and chlorine (Cl)?

Back

Ionic bond: This bond is formed when electrons are transferred from one atom to another, resulting in the formation of charged ions.

Front

What type of bond is represented by the sharing of electron pairs between atoms?

Back

Covalent bond: This bond occurs when two atoms share one or more pairs of electrons.

Front

What is the ionic formula for the compound formed between calcium (Ca) and phosphorus (P)?

Back

Ca₃P₂: This formula indicates that three calcium ions combine with two phosphorus ions.

Front

What is the Lewis structure for BF₃?

Back

The Lewis structure shows boron (B) in the center with three fluorine (F) atoms surrounding it, each connected by a single bond.

Front

What do positive ions tend to do?

Back

Lose electrons: Positive ions are formed when atoms lose one or more electrons.

Front

What is a metallic bond?

Back

Metallic bond: A bond formed by the attraction between positively charged metal ions and the electrons that are free to move around them.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of 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 eight electrons.

Front

What is an example of a molecule with a double covalent bond?

Back

O₂ (Oxygen): Each oxygen atom shares two pairs of electrons.

Front

What is the charge of a calcium ion (Ca²⁺)?

Back

+2: Calcium loses two electrons to form a positive ion.
