Electron Configurations & Orbital Notation-Garza

Front

What is an electron configuration?

Back

An electron configuration is the distribution of electrons in an atom's orbitals, indicating the energy levels and sublevels occupied by electrons.

Front

What does the notation 1s² represent?

Back

The notation 1s² indicates that there are 2 electrons in the 1s orbital, which is the lowest energy level.

Front

What is the significance of the Aufbau principle in electron configurations?

Back

The Aufbau principle states that electrons fill orbitals starting from the lowest energy level to the highest.

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, which must have opposite spins.

Front

What does the term 'valence electrons' refer to?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

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

Back

The number of valence electrons can be determined by the group number of the element in the periodic table.

Front

What is the electron configuration for Calcium (Ca)?

Back

The electron configuration for Calcium (Ca) is 1s² 2s² 2p⁶ 3s².

Front

What is the electron configuration for a 2+ ion of Magnesium (Mg)?

Back

The electron configuration for a 2+ ion of Magnesium (Mg) is 1s² 2s² 2p⁶.

Front

What is the difference between an atom and an ion?

Back

An atom is neutral with equal numbers of protons and electrons, while an ion has a net charge due to the loss or gain of electrons.

Front

What is the significance of the p4 electron configuration?

Back

The p4 electron configuration indicates that an element has 4 electrons in its p orbitals, characteristic of Group 16 elements.
