M-U2-Zone 5- Electron Configuration

Front

What is electron configuration?

Back

Electron configuration is the distribution of electrons in an atom's orbitals, indicating how many electrons occupy each energy level and sublevel.

Front

How many total orbitals are in the 3rd energy level?

Back

There are 9 total orbitals in the 3rd energy level: 1 s orbital, 3 p orbitals, and 5 d orbitals.

Front

What is the maximum number of electrons in an orbital?

Back

The maximum number of electrons in a single orbital is 2.

Front

What is the formula to calculate the maximum number of electrons in an energy level?

Back

The formula is 2n^2, where n is the principal quantum number (energy level).

Front

How many p type orbitals are in the 2nd energy level?

Back

There are 3 p type orbitals in the 2nd energy level.

Front

What is the electron configuration for a neutral atom of oxygen?

Back

Front

What is the significance of valence electrons?

Back

Valence electrons are the outermost electrons of an atom and are important for chemical bonding and reactivity.

Front

Which elements have the same valence shell configuration as magnesium?

Back

Calcium (Ca) has the same valence shell configuration as magnesium (Mg), both having 2 valence electrons in the outermost shell.

Front

What is the ground state electron configuration for a neutral atom of carbon?

Back

Front

What is the difference between ground state and excited state electron configurations?

Back

Ground state configuration is the lowest energy arrangement of electrons, while excited state configuration occurs when electrons absorb energy and move to higher energy levels.
