Chemical Bonding and Properties (Warm-Up)

Front

What determines the number of valence electrons an element has?

Back

The group the element is in.

Front

What is the electron dot diagram for Nitrogen?

Back

Nitrogen has 5 valence electrons, represented as: •N• (with 5 dots around the N symbol).

Front

Why is Neon considered a noble gas?

Back

Because it is stable, nonreactive, and has 8 valence electrons.

Front

Why do elements bond?

Back

To become stable and have a complete outer energy level.

Front

What type of bond occurs between nonmetals?

Back

Covalent bond.

Front

What is a covalent bond?

Back

A chemical bond formed when two nonmetals share electrons.

Front

What are valence electrons?

Back

Electrons in the outermost shell of an atom that determine its chemical properties.

Front

What is the octet rule?

Back

Atoms tend to bond in such a way that they have eight electrons in their valence shell.

Front

What is an ionic bond?

Back

A chemical bond formed between a metal and a nonmetal through the transfer of electrons.

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.
