Patterns of the Periodic Table: Finding Shells and Valence Electrons ... - Free Printable

To solve the problem, we need to fill in the missing information in the table based on the given data. The table includes columns for "Group / valence e's," "Period / Shell," "Symbol," "Element," and "M, NM, MD." Let's break it down step by step.

Step 1: Understand the Columns

- Group / valence e's: Refers to the group number in the periodic table or the number of valence electrons.
- Period / Shell: Refers to the period number in the periodic table or the number of electron shells.
- Symbol: The chemical symbol of the element.
- Element: The name of the element.
- M, NM, MD: Indicates whether the element is a Metal (M), Nonmetal (NM), or Metalloid (MD).

Step 2: Fill in the Missing Information

We will use our knowledge of the periodic table to fill in the missing values.
