Semester Exam Review

Front

What is the lowest energy orbital that can receive an electron?

Back

The lowest energy orbital is the one that is most stable and can accommodate an electron.

Front

What element is represented by the electron configuration 1s² 2s² 2p⁶ 3s²?

Back

The element is magnesium.

Front

How do aluminum (Al³⁺) and oxide (O²⁻) bond together?

Back

They bond together to form Al₂O₃.

Front

What is the main reason for the similar chemical behavior of elements in the same family?

Back

They have similar electron configurations.

Front

Which molecule has a linear molecular geometry?

Back

CO₂ has a linear molecular geometry.

Front

Define electron configuration.

Back

Electron configuration is the distribution of electrons in an atom's orbitals.

Front

What is the significance of the octet rule in bonding?

Back

The octet rule states that atoms tend to bond in a way that gives them eight electrons in their valence shell, achieving stability.

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed by the sharing of electron pairs between atoms.

Front

What is an ionic bond?

Back

An ionic bond is a chemical bond formed through the electrostatic attraction between oppositely charged ions.

Front

What is the role of valence electrons in chemical bonding?

Back

Valence electrons are the outermost electrons that participate in chemical bonding.
