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 does oxygen typically react based on its valence electrons?

Back

Oxygen has 6 valence electrons and typically gains 2 electrons to achieve a full outer shell.

Front

What type of bond occurs between two metals?

Back

A metallic bond occurs between two metals.

Front

What is the significance of the element symbol in chemical diagrams?

Back

The element symbol represents the specific element in a chemical diagram, indicating its identity.

Front

How does bromine (Br) behave in terms of electron gain or loss?

Back

Bromine typically gains electrons, specifically one electron, to achieve a full outer shell.

Front

What type of bond is CO2 an example of?

Back

CO2 is an example of a covalent bond, where atoms share electrons.

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.

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.

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 happens to metals during bonding?

Back

Metals tend to lose electrons during bonding, forming positive ions.
