A mixture where individual components can be visually identified.

The smallest unit of an element that retains its chemical properties.

A charged atom formed by gaining or losing electrons.

A positively charged ion formed when an atom loses electrons.

A negatively charged ion formed when an atom gains electrons.

The number of protons in an atom's nucleus, determining the element's identity.

The sum of protons and neutrons in an atom's nucleus, indicating its atomic mass.

The unit used to measure the mass of atoms.

Anything that has mass and takes up space.

A substance with a constant composition, meaning all parts are the same and its properties remain constant.

A pure substance made up of only one type of atom, like oxygen or aluminum.

A pure substance made up of two or more elements combined in a fixed ratio, like water (H2O) or salt (NaCl).

A combination of two or more substances that are not chemically combined.

A mixture where all parts look the same throughout, like saltwater or air.

A mixture where the different parts can be seen easily, like sand and water.

Another name for a homogeneous mixture, often used in chemistry.

Atoms of the same element that have the same number of protons but different numbers of neutrons, resulting in different atomic masses.

The number of protons in an atom, which determines the element.

An isotope with an unstable nucleus that emits radiation to become more stable.

The total number of protons and neutrons in an atom's nucleus.

A standardized system used in Canada to identify potentially hazardous materials, often found on product labels.

A document providing detailed information about a chemical product's hazards, handling, and safety measures.

The chemical supplier prepares it, and it's updated every three years.

Workplace Hazardous Materials Information System (WHMIS) labels and MSDS's are designed to inform workers about potential dangers of chemical products and how to work safely with them.

It includes detailed information about the chemical's properties, potential hazards, and safety precautions.

It's important to access and review the MSDS for any chemical you use in the workplace, to ensure safe handling and prevent issues.

A system designed to communicate hazards associated with chemicals used in the workplace.

A set of standardized symbols used to alert workers to specific hazards posed by chemicals.

A symbol depicting a skull and crossbones, indicating the presence of a chemical that causes immediate toxic effects.

A symbol depicting a flame, indicating the presence of a flammable or combustible material.

A symbol depicting a person with a respiratory mask and hand in front of a gas cloud, indicating a chemical that poses a health hazard.

A system used to supplement the WHMIS 2015 symbols, providing numerical ratings for health, flammability, physical hazards and required personal protection.

Numbers from 0 to 4 are used to indicate the level of danger, with 0 representing no danger and 4 representing the highest level of danger.

Letters are used to indicate the type and level of personal protective equipment needed when handling a chemical.
