Chemical Bonding

Front

What are dispersion forces?

Back

Dispersion forces, also known as London dispersion forces, are weak intermolecular forces that arise from temporary shifts in electron density in atoms or molecules, leading to temporary dipoles.

Front

Which substance has only dispersion forces?

Back

CH₄ (methane) has only dispersion forces.

Front

What do nonmetals typically do when forming ionic bonds?

Back

Nonmetals typically gain electrons when they form ionic bonds.

Front

Front

What is the chemical name for NI₃?

Back

The chemical name for NI₃ is nitrogen triiodide.

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, typically between a metal and a nonmetal.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond formed when two atoms share one or more pairs of electrons.

Front

What is the difference between ionic and covalent compounds?

Back

Ionic compounds are formed from the transfer of electrons from metals to nonmetals, while covalent compounds are formed from the sharing of electrons between nonmetals.

Front

What is a cation?

Back

A cation is a positively charged ion that is formed when an atom loses one or more electrons.
