Give the steps used to make a simple periodic table

The primary organizing principle of the periodic table is the atomic number (number of protons). Elements are arranged in increasing order of atomic number. A secondary principle is the recurrence of chemical properties.

Periods are horizontal rows. Each new period starts when a new electron shell begins to fill. There are typically 7 periods.

Groups are vertical columns. Elements within the same group generally have similar chemical properties because they have the same number of valence electrons. There are 18 groups.

• Metals: Typically found on the left and center (e.g., alkali metals, alkaline earth metals, transition metals, basic metals). They are generally shiny, good conductors of heat and electricity, and malleable.
• Nonmetals: Found on the upper right (e.g., halogens, noble gases, other nonmetals). They are generally poor conductors and brittle.
• Metalloids: Found along the "staircase" line between metals and nonmetals (e.g., Boron, Silicon, Germanium). They have properties intermediate between metals and nonmetals.

• Start with Hydrogen (atomic number 1) in the top left.
• Move across the first period to Helium (atomic number 2) in the top right.
• Continue with Lithium (atomic number 3) starting the second period, and so on.
• Ensure elements with similar properties (e.g., all noble gases) fall into the same vertical group.
• Remember to include the Lanthanides and Actinides series, usually placed below the main table for compactness.

For a simple table, each element's box should include:

• Atomic Number: (e.g., 1 for Hydrogen)
• Element Symbol: (e.g., H for Hydrogen)
• Element Name: (e.g., Hydrogen)
• Atomic Mass: (e.g., 1.008 for Hydrogen)

• Create a grid with 7 rows and 18 columns (or fewer if simplifying by combining groups).
• Color-code different categories (metals, nonmetals, metalloids) for clarity.
• Add a legend to explain the color coding and any symbols used.
