Flashcard 6- 1 Three Types of Bonds

Front

What is a valence electron?

Back

An electron that is found in the outermost shell of an atom.

Front

Which element has a greater electronegativity: N or C?

Back

N (Nitrogen) has a greater electronegativity than C (Carbon).

Front

What charge will an element have as an ion if it gains electrons to achieve 8 valence electrons?

Back

-1 (It will gain electrons to achieve a full outer shell).

Front

How do covalent bonds form?

Back

Covalent bonds form by sharing valence electrons between atoms.

Front

Which of the following is NOT formed by a covalent bond: K2S, H2O, I2, CO2?

Back

K2S (Potassium sulfide is formed by ionic bonds).

Front

What is an ionic bond?

Back

An ionic bond is formed when one atom donates an electron to another atom, resulting in attraction between oppositely charged ions.

Front

What is electronegativity?

Back

Electronegativity is the tendency of an atom to attract electrons in a chemical bond.

Front

What type of bond is formed between two nonmetals?

Back

Covalent bond.

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 8 electrons.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where electrons are shared unequally between two atoms, resulting in partial charges.
