Electron Configurations Independent Practice

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 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 and counting the electrons in that level.

Front

What is the Noble Gas Abbreviation for an element?

Back

The Noble Gas Abbreviation is a shorthand notation for an electron configuration that uses the electron configuration of the nearest noble gas to simplify the representation.

What is the electron configuration for tin (Sn)?

Back

The electron configuration for tin is [Kr] 5s² 4d¹⁰ 5p².

Front

What shape does the s sublevel resemble?

Back

The s sublevel resembles a sphere.

Front

What is the abbreviated electron configuration for barium (Ba)?

Back

The abbreviated electron configuration for barium is [Xe] 6s².

Front

What does a +1 charge indicate about an atom's electron configuration?

Back

A +1 charge indicates that the atom has lost one electron compared to its neutral state.

Front

What is the electron configuration for a neutral oxygen atom?

Back

The electron configuration for a neutral oxygen atom is 1s² 2s² 2p⁴.

Front

How many total electrons are in a neutral neon atom?
