Ionic and Covalent Bonding, Lewis Dots

Front

What is the Lewis dot model?

Back

A diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.

How many valence electrons does Lithium have?

Back

1

Front

What is the main characteristic of ionic bonds?

Back

Ionic bonds are formed by the transfer of electrons from one atom to another.

Front

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

Back

2

Front

What type of bond is formed when two atoms share electrons?

Back

Covalent bond.

Front

What is a double bond?

Back

A type of covalent bond where two pairs of electrons are shared between two atoms.

Front

Which molecule has a double bond?

Back

Carbon dioxide (CO2).

Front

How many covalent bonds does carbon need to form a full octet?

Back

4

Front

What is the octet rule?

Back

Atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

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.
