Regular Electron Configuration Test

Front

What is electron configuration?

Back

The distribution of electrons in an atom's orbitals, represented by a series of numbers and letters indicating the energy levels and sublevels.

What is the electron configuration for Arsenic (As)?

Back

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p³

Front

What is the electron configuration for As^-2?

Back

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p¹ (Arsenic gains 2 electrons).

Front

How many electrons can fit in the p sublevel?

Back

A p sublevel can hold a maximum of 6 electrons.

Front

What noble gas is used for shorthand electron configuration of Plutonium (Pu)?

Back

Radon (Rn) is used for shorthand configuration.

Front

How many sublevels are in the 3rd energy level?

Back

There are 3 sublevels in the 3rd energy level: s, p, and d.

Front

What is the maximum number of electrons in the 3rd energy level?

Back

The maximum number of electrons in the 3rd energy level is 18.

Front

What is the significance of noble gases in electron configuration?

Back

Noble gases have full outer electron shells, making them stable; they are used as reference points in shorthand electron configurations.

Back

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁵.

Front

What does the notation '4s²' indicate?

Back

It indicates that there are 2 electrons in the 4s sublevel.
