Final Exam Review

Front

What type of bond forms when electrons are transferred from one atom to another?

Back

Ionic bond: A type of chemical bond that occurs when one atom transfers electrons to another atom, resulting in the formation of charged ions that attract each other.

Front

What atom is represented by the symbol 'N'?

Back

Nitrogen: A chemical element with the symbol 'N' and atomic number 7, essential for life and a key component of amino acids and nucleic acids.

Front

What is the molecular shape of a molecule with three bonding pairs and no lone pairs?

Back

Trigonal Planar: A molecular geometry where three atoms are arranged around a central atom in a flat, triangular shape.

Front

Which Lewis dot structure correctly represents the molecule fluorine (F2)?

Back

Lewis Dot Structure B: The correct representation shows each fluorine atom sharing one pair of electrons.

Front

Who proposed that all matter is made of a combination of earth, fire, wind, and water?

Back

Aristotle: An ancient Greek philosopher who theorized that all matter was composed of four fundamental elements.

Front

What is an ionic bond?

Back

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

Front

What is the atomic number of Nitrogen?

Back

7: The atomic number of nitrogen, indicating it has seven protons in its nucleus.

Front

What is the shape of a molecule with four bonding pairs and no lone pairs?

Back

Tetrahedral: A molecular geometry where four atoms are symmetrically arranged around a central atom.

Front

What is the significance of Lewis dot structures?

Back

Lewis dot structures visually represent the valence electrons of atoms and how they bond with each other.

Front

What is the difference between covalent and ionic bonds?

Back

Covalent bonds involve the sharing of electrons between atoms, while ionic bonds involve the transfer of electrons from one atom to another.
