Chemical Properties of Zinc

Zinc is a moderately reactive metal. It readily forms compounds with other elements, and reacts with acids, alkalis, and other non-metals. It does not react with water. Zinc is known for its ability to undergo galvanization, a process of applying a protective zinc coating to steel or iron to prevent rusting.

Uses of Zinc

Zinc is commonly used in a variety of applications, including:

Galvanization of steel
Production of brass and bronze
As a component in batteries
In the production of zinc oxide, which is used in rubber manufacturing, ceramics, and as a pigment in paints
In dietary supplements and as an ingredient in various pharmaceutical products

What is science?

The resources above cover the following skills:

LIFE SCIENCE

Ecosystems: Interactions, Energy, and Dynamics

Obtain information from literature and other media to illustrate that there are many different kinds of living things and that they exist in different places on land and in water (e.g., woodland, tundra, desert, rainforest, ocean, river).

EARTH AND SPACE SCIENCE

Earth’s Systems

Make observations from media to obtain information about Earth’s events that happen over a short period of time (e.g., tornados, volcanic explosions, earthquakes) or over a time period longer than one can observe (e.g., erosion of rocks, melting of glaciers).

Collect and evaluate data to identify water found on Earth and determine whether it is a solid or a liquid (e.g., glaciers as solid forms of water; oceans, lakes, rivers, streams as liquid forms of water).
