Unit 4 Lesson 2 Practice

Front

What is the Octet Rule?

Back

The Octet Rule states that atoms tend to react with each other to achieve a full outer shell of 8 electrons, resembling the electron configuration of noble gases.

Front

How many valence electrons does Calcium (Ca) have?

Back

Calcium has 2 valence electrons.

Front

What is the charge of an atom that has lost one electron?

Back

The charge of an atom that has lost one electron is +1.

Front

What is the electron configuration of Chlorine (Cl)?

Back

The electron configuration of Chlorine is 1s² 2s² 2p⁶ 3s² 3p⁵.

Front

How many valence electrons does an Oxygen atom have?

Back

Oxygen has 6 valence electrons.

Front

Define 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 valence electrons in chemical bonding?

Back

Valence electrons determine how an atom can bond with other atoms, influencing the formation of molecules.

Front

What happens to the charge of an atom when it gains an electron?

Back

When an atom gains an electron, it becomes negatively charged, with a charge of -1.

Front

What is the electron configuration for a neutral atom of Sodium (Na)?

Back

The electron configuration for Sodium is 1s² 2s² 2p⁶ 3s¹.

Front

How many electrons can the outermost shell hold according to the Octet Rule?

Back

The outermost shell can hold a maximum of 8 electrons according to the Octet Rule.
