The table is also arranged in vertical columns called “groups” or “families” and horizontal rows called “periods.” Each arrangement is significant. The elements in each vertical column or group have similar properties. Group 1 elements all have the same valence or outer shell electrons in their outer shells (one valence electron).
2.3: Families and Periods of the Periodic Table - Chemistry LibreTexts
Periods – horizontal rows, ordered in increasing size and atomic number, elements typically have same number of energy levels. Groups – families, vertical column, have similar physical and chemical properties. The current IUPAC system numbers the groups 1-18. An older system (still in use) identifies each group by a number and the letter A ...

Each of the 109 known elements has its own set of characteristic properties. These range from solid to gas, lustrous to dull, low to high melting points, various colors, and so on. The elements are arranged in the periodic table into groups or families (vertical columns) and periods or rows (horizontal rows).

Point out that the Periodic Table is also organized along a vertical and horizontal axis based on the properties of the elements. Hand out the periodic table information page for the students to read. Explain that Dimitri Mendeleev, a Russian chemist, was the first to publish the classification of the elements that gave us the format we use today.

Nov 21, 2006 · Periods are horizontal rows on the periodic table. Period 1 has hydrogen and helium. Electrons in period 1 are only in one principal energy level. “Valence” electrons are in the first principal energy level. What are valence electrons? Write your answer in the space below. Groups: are vertical columns (families). Groups run 1-18.
