Electron Configurations

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

Front

How many valence electrons does a noble gas have?

Back

Noble gases have 8 valence electrons, making them stable and unreactive.

Front

What is the maximum number of electrons that can occupy a single orbital?

Back

A single orbital can hold a maximum of 2 electrons.

Front

What is the electron configuration for Gold (Au)?

Back

The electron configuration for Gold is [Xe] 6s² 4f¹⁴ 5d⁹.

Front

How many total electrons does Silicon (Si) have?

Back

Front

What is the significance of the electron configuration in determining an element's chemical properties?

Back

The electron configuration determines how an element interacts with other elements, influencing its reactivity and bonding behavior.

Front

What is an orbital in the context of electron configurations?

Back

An orbital is a region in an atom where there is a high probability of finding electrons.

Front

How do you determine the number of valence electrons from an electron configuration?

Back

The number of valence electrons can be determined by looking at the highest energy level (n) in the electron configuration.

Front

What is the electron configuration for a Chlorine (Cl) atom?

Back

The electron configuration for Chlorine is [Ne] 3s² 3p⁵.

Front

What is the relationship between electron configuration and the periodic table?

Back

The electron configuration of an element helps to determine its position in the periodic table and its group number.
