Atoms and Molecules Quiz

What is the smallest particle of a compound that retains the properties of that compound?

What is the basic unit of an element that retains the chemical properties of that element?

Which subatomic particle has a negative charge?

Explain the structure of an atom and the arrangement of its subatomic particles.

Describe the role of protons, neutrons, and electrons in the structure of an atom.

How does the arrangement of electrons in an atom relate to its chemical properties?

Atomic Structure

The smallest particle of a compound that retains the properties of that compound is a molecule.
The basic unit of an element that retains the chemical properties of that element is an atom.

Subatomic Particles

Electrons are subatomic particles with a negative charge.
Protons are subatomic particles with a positive charge, located in the nucleus of an atom.
Neutrons are subatomic particles with no charge, located in the nucleus of an atom.

Atomic Structure and Arrangement

An atom consists of three main parts: protons, neutrons, and electrons.
Protons and neutrons are located in the nucleus (center) of the atom.
Electrons orbit around the nucleus in energy levels or shells.

Role of Subatomic Particles

Protons determine the identity of an element and its chemical properties.
Neutrons contribute to the mass of an atom and affect the atom's physical properties.
Electrons participate in chemical bonding and determine the chemical properties of an element.

Electron Arrangement and Chemical Properties

The arrangement of electrons in an atom, or electron configuration, relates directly to its chemical properties.
The number of electrons in the outermost energy level (valence shell) determines an element's reactivity and ability to form bonds.
