The Periodic Table Organized
Grade 8 · Science · Chemistry · Kentucky, USA
Lesson Summary
See how the periodic table groups elements by their properties.
Explanation
The periodic table arranges all known elements by atomic number (number of protons). Elements in the same column, called a group, share similar chemical properties. Elements in the same row, called a period, have the same number of electron shells. Metals are on the left, nonmetals on the right, and metalloids sit along the dividing line. The table's organization makes it possible to predict how elements will behave and react with each other.
Practice Questions
Q1: Why are elements in the same group similar?
Answer: They have the same number of electrons in their outer shell, which determines how they bond and react with other elements.
Q2: Where are metals found on the periodic table?
Answer: On the left side and in the center of the table. Nonmetals are on the upper right.
Q3: What does the atomic number tell you about an element?
Answer: It tells you the number of protons in each atom of that element, which defines what element it is.
