Your Privacy Rights. Skills to Develop Give the name and location of specific groups on the periodic table, including alkali metals, alkaline earth metals, noble gases, halogens, and transition metals. Explain the relationship between the chemical behavior of families in the periodic table and their electron configurations.
Identify elements that will have the most similar properties to a given element. Families of the Periodic Table Remember that Mendeleev arranged the periodic table so that elements with the most similar properties were placed in the same group. Periods of the Periodic Table If you can locate an element on the Periodic Table, you can use the element's position to figure out the energy level of the element's valence electrons.
Summary The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods. Vocabulary Group family : A vertical column in the periodic table.
Alkali metals: Group 1A of the periodic table. Nuclear family : This is also known as the conjugal family or family of procreation. Nuclear families are comprised of married partners and their offspring. This is common in industrial societies, but it is not the most common type of family in the world, although the practice is spreading through modern development.
Some anthropologists identify a second type of nuclear family, the non-conjugal family. In this type of nuclear family, there is one parent with dependent children. Additionally, there is the polygymous family, which is comprised of multiple spouses and dependent children Lavenda and Schultz ; note that Lavenda and Schultz refer to a polygynous family, not a polygymous family, but that term does not encompass a married woman living with multiple husbands and dependent children.
Extended family : The extended family is the most common type of family in the world. Extended families include at least three generations: grandparents, married offspring, and grandchildren.
Joint family : Joint families are composed of sets of siblings, theirs spouses, and their dependent children. Blended family : Blended families are becoming more common, especially in industrial societies like the United States.
