What is element Short answer?
An element is a substance that cannot be broken down into any other substance. There are about 100 elements, each with its own type of atom. Everything in the universe contains the atoms of at least one or more elements. The periodic table lists all the known elements, grouping together those with similar properties.
What are the 2 main types of elements?
The elements can also be divided into two main groups, the metals and the non-metals. Metals are typically have a metallic sheen (shiny) are malleable (bendable) and conduct electricity. Nonmetals typically do not show these properties.
