What is an atom?

• An atom is the building block of all matter.

• Atoms are composed of particles called protons, electrons, and neutrons.

• Atoms can join together to form molecules, which in turn form most of the objects around you. Example - Water

  H₂O.

Chemical Element

• Atomic number- tells the number of protons, electrons and the location of the element on the Periodic Table

• Atomic Mass- the sum of the protons and neutrons in the nucleus of the atom

• To find the number of neutrons, subtract the atomic number from the atomic mass

The Periodic Table of the Elements

• display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties

• The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right.

• The columns, called groups, contain elements with similar chemical behaviors. 

Multiple Choice

Which of the following statements is true about how the periodic table is organized?

• The elements are organized by their size

• The elements are organized by the date they were discovered.

• The elements are organized by the scientists who discovered them

• The elements are organized by their properties.
