Valence Electrons and Lewis Dot Structures

Front

What is a lone pair?

Back

A pair of non-bonding electrons.

Front

What type of bond involves three pairs of shared electrons?

Back

Triple bond.

Front

How many valence electrons do elements in Group 2A have?

Back

2.

Front

What is a double bond?

Back

Two pairs of electrons shared between two atoms.

Front

How many double bonds are present in CCl4?

Back

0.

Front

What are valence electrons?

Back

Electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is the significance of Lewis Dot Structures?

Back

They visually represent the valence electrons of an atom and how they bond with other atoms.

Front

What does a single bond represent in terms of electron pairs?

Back

One pair of electrons shared between two atoms.

Front

How can you determine the number of valence electrons in an element?

Back

By looking at its group number in the periodic table.

Front

What is the octet rule?

Back

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