Summative Flashcard 11/20

Front

What is the reactivity of fluorine compared to neon?

Back

Fluorine is more reactive than Neon.

Front

What are the characteristics of covalent bonds?

Back

Covalent bonds involve sharing electrons, have lower melting points, and occur between two or more nonmetals.

Front

What is the correct Lewis dot structure for the molecule fluorine (F2)?

Back

The correct Lewis dot structure is represented by option B.

Front

What type of bond is formed when electrons are transferred from one atom to another?

Back

Ionic bond.

Front

How many valence electrons does an oxygen atom have?

Back

Oxygen has 6 valence electrons.

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that involves the transfer of electrons from one atom to another, resulting in the formation of ions.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.

Front

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

Back

A polar covalent bond occurs when electrons are shared unequally between atoms, while a nonpolar covalent bond occurs when electrons are shared equally.
