Use the Periodic Table to determine which of the following lists consists of elements that have the MOST similar chemical properties.
Answers
Answer:
The periodic table shows all the elements and their physical properties; it is arranged based on atomic numbers and electron configurations.
Determining Chemical Properties using the Periodic Table
Chemical properties of each element are determined by the element’s electronic configuration, and particularly by its outermost valence electrons. An element’s location in the periodic table is largely dependent on its electrons; the number of valence shell electrons determines its group, and the type of orbital in which the valence electrons lie in determines the element’s block. In addition, the total number of electron shells an atom determines which period it belongs to. Because of its structure, the periodic table has become an extremely useful tool for assessing and predicting elemental and chemical trends.
