On the "Periodic Table and Electron-Dot diagrams, draw the electron-dot diagrams for the elements. Examine the Group number (along the top) and the number of valence electrons for the elements. For the "s" elements, what is the relationship between the Group number and the # of valence electrons?

Periodic Table. Organization of elements. Periods: horizontal rows across the periodic table. Groups/families: vertical columns in the periodic table. Elements in the same group have the same number of valence electrons and have other similar properties. Types of Elements. Metals: Nonmetals; Metalloids/Semi-metals; Ductile – roll into wires . Malleable – flatten into thin sheets. Brittle ...

Groups within the periodic table are the vertical columns – there are groups 1-7 plus group 0 and the transition metals. The group number tells you the number of electrons which you find in the outer shell. Periods within the periodic table are the horizontal rows – there are 7 periods. The period tells you the number of shells of electrons which are present.

The present organization of the elements is a product of the first periodic table published by Dmitri Mendeleev in 1869. The amazing accuracy of his predictions has been very important to chemists in this century. However, the basis of his arrangement was the atomic masses of the elements. This approach proved incorrect, as it would have placed some elements in a family with dissimilar ...

Periodic Table Worksheet Tier 1 and 2. 1. Periodic means . Examples of periodic properties: 2. What is a group (or family)? What is a period? 3. How can you determine the number of electrons in an element’s outer energy level by the group it’s in? 4. What is the octet rule? 5. Why do elements that make positive ions occur on the left side of the periodic table while those that . make ...

Each column or group in the periodic table is called a family. Elements are organized into families according to their physical and chemical properties. Identify the elements that belong to each family based on the number of valence electrons. Give the name and symbol for each element.

The alkali metals, found in-group 1 of the periodic table (formerly known as group IA), are very reactive metals that do not occur freely in nature. These metals have only one electron in their outer shell. Therefore, they are ready to lose that one electron in ionic bonding with other elements. As with all metals, the alkali metals are malleable, ductile, and are good conductors of heat and ...

Zeff increases slightly down a group. In the periodic table, elements are divided into: the s-block (contains reactive metals of Group 1A (1) and 2A (2)), the p-block (contains metals and nonmetals of Group 3A (13) through 8A (18)), the d-block (contains transition metals (Group 3B (3) through Group (2B (12)), and . the f-block (contains lanthanide and actinide series or inner transition ...
