Physical Science Definitions Practice

the arrangement of the elements in order of their atomic numbers so that elements with similar properties appear in the same vertical column or group.

• Periodic table
• Nucleus
• Electron cloud
• Crystal

atoms that have a positive or negative charge because they have unequal numbers of protons and electrons
