The elements in each vertical column or group have similar properties. The elements in each group have the same number of valence electrons which determines the elements chemical properties including reactivity. The valence electrons are the electrons on the outer most energy level of the atom. There are 18 groups (columns) on the periodic table.

group. For all groups, the elements in that group have similar chemical properties. Section 5.2 – Exploring the Periodic Table. The Role of Electrons. The periodic table is organized by atomic number, which is the number of protons in an atom. The periodic trends in the periodic table are the result of electron arrangement. Specifically, the ...

The purpose of this lab is to observe how certain properties of elements tend toward a periodic similarity when the elements are arranged in order of increasing atomic number; to note that elements (and ions of those elements) in the same vertical column (family) of the periodic table have similar properties; to note that elements (and ions of ...

It is called the Periodic Table because elements with similar properties appear at regular intervals. Elements is the same group have similar chemical properties because they have the same number of electrons in their outer shell. Before electrons, protons and neutrons were discovered, scientists put the elements in order of their atomic weights.

The Periodic Table | CHEM 1305: General Chemistry I—Lecture
Elements within each group have similar . physical. and chemical properties. Some of the physical properties used to distinguish between the three groups are: Luster = the ability of a substance to reflect light. Usually the descriptive words are either . metallic or non-metallic. Conductivity = the ability of the substance to conduct . electricity
