Chemical Bonding Review

Front

What kind of bond forms when atoms transfer electrons?

Back

Ionic bond: A type of chemical bond that occurs when one atom transfers electrons to another, resulting in the formation of charged ions.

Front

If an atom gains two electrons, what charge will it have?

Back

-2: The atom will have a negative charge of -2 because it has more electrons than protons.

Front

If an atom loses two electrons, what charge will it have?

Back

+2: The atom will have a positive charge of +2 because it has more protons than electrons.

What type of bond is formed between beryllium (Be) and fluorine (F)?

Back

Ionic bond: Beryllium transfers electrons to fluorine, resulting in an ionic bond.

Front

What type of bond is formed between selenium (Se) and chlorine (Cl)?

Back

Covalent bond: Selenium and chlorine share electrons, resulting in a covalent bond.

Define ionic bond.

Back

Ionic bond: A chemical bond formed through the electrostatic attraction between oppositely charged ions.

Front

Define covalent bond.

Back

Covalent bond: A chemical bond formed when two atoms share one or more pairs of electrons.

Front

What is the charge of a sodium ion (Na+) after losing one electron?

Back

+1: Sodium loses one electron, resulting in a positive charge of +1.

Front

What is the charge of a chloride ion (Cl-) after gaining one electron?

Back

-1: Chlorine gains one electron, resulting in a negative charge of -1.

Front

What is the octet rule?

Back

Octet rule: Atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.
