Explain the concept of electron configuration.

• Electron configuration is the study of electron behavior in a vacuum.

• Electron configuration refers to the movement of electrons between different atoms.

• Electron configuration is the arrangement of electrons in an atom's electron shells or energy levels based on the Aufbau principle, Pauli exclusion principle, and Hund's rule.

• Electron configuration is the process of arranging protons in an atom's nucleus.

What is the purpose of orbital diagrams?

• To visually represent the arrangement of electrons in an atom's orbitals.

• To determine the atomic number of an element

• To calculate the boiling point of a substance

• To represent the phases of the moon

Why are valence electrons important in chemical reactions?

• Valence electrons are not involved in any chemical reactions.

• Valence electrons are responsible for determining the atomic number of an element.

• Valence electrons are only found in noble gases.

• Valence electrons are involved in forming chemical bonds.

Write the electron configuration for nitrogen.

• 1s2 2s3 2p2

• 1s2 2s2 2p4

• 1s2 2s2 2p3

• 1s2 2s1 2p4

Illustrate the orbital diagram for sulfur.

• 1s2 2s2 2p6 3s1 3p4

• 1s2 2s2 2p6 3s2 3p4

• 1s2 2s2 2p5 3s2 3p4

• 1s2 2s2 2p6 3s2 3p3

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

• Count the number of protons in the nucleus

• Check the atomic mass of the element

• Look at the group number of the element on the periodic table.

• Look at the period number of the element on the periodic table

Describe the significance of electron configuration in predicting chemical properties.

• Electron configuration is crucial in predicting chemical properties as it determines the number and distribution of valence electrons, which directly impact an element's behavior in chemical reactions.

• Electron configuration has no impact on chemical properties

• Valence electrons are not relevant in chemical reactions

• Chemical properties are solely determined by the number of protons in an atom
