e- Configuration & Periodic Trends

Front

What is electron configuration?

Back

The distribution of electrons in an atom's orbitals, indicating the energy levels and sublevels occupied by electrons.

Front

What is the octet rule?

Back

Atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons, leading to greater stability.

Front

What does isoelectronic mean?

Back

Two or more species (atoms, ions, or molecules) that have the same electron configuration.

Front

Which element has the electron configuration 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰?

Back

Zinc (Zn).

Front

What is electronegativity?

Back

A measure of the tendency of an atom to attract a bonding pair of electrons.

Front

Which element has the greatest electronegativity?

Back

Fluorine (F).

Front

What is the electron configuration for Technetium?

Back

[Kr] 5s² 4d⁵.

Front

How many electrons does an element with the configuration 1s² 2s² 2p⁴ need to satisfy the octet rule?

Back

2 electrons.

Front

What is the significance of the periodic table in relation to electron configuration?

Back

The periodic table organizes elements by increasing atomic number and shows trends in electron configurations and properties.

Front

What are the main blocks of the periodic table?

Back

s-block, p-block, d-block, and f-block, corresponding to the electron configurations of the elements.
