PS1-1: Develop models to describe the atomic composition of simple molecules and extended structures.

drbscience — 2023-10-06 04:05:25 UTC

Emphasis is on developing models of molecules that vary in complexity. Examples of simple molecules could include ammonia and methanol. Examples of extended structures could include sodium chloride or diamonds. Examples of molecular-level models could include drawings, 3D ball and stick structures, or computer representations showing different molecules with different types of atoms.

Assessment does not include valence electrons and bonding energy, discussing the ionic nature of subunits of complex structures, or a complete description of all individual atoms in a complex molecule or extended structure is not required.

Atom: The basic building block of matter. It is the smallest unit of an element that retains the chemical properties of that element.

Molecule: A group of two or more atoms chemically bonded together. It is the smallest unit of a compound that retains its chemical properties.

Model: A simplified representation or description of a system or concept that helps us understand and explain it.

Atomic Composition: Refers to the types and numbers of atoms that make up a molecule or a material.

Simple Molecule: A molecule composed of a few atoms bonded together.

Extended Structure: A larger arrangement of atoms or molecules that repeat in a regular pattern, forming a solid material.

Chemical Bond: The force of attraction that holds atoms together in a molecule or a compound.

Element: A pure substance made up of only one type of atom.

Compound: A substance composed of two or more different elements chemically combined in a fixed ratio.

Composition: The nature and arrangement of the different parts or elements that make up something.
