   Feb 2, 2024 · 2 February 2024. Properties of the Elements in Period 3. Elements in the periodic table are arranged in order of increasing atomic number and placed in vertical columns (groups) and horizontal rows (periods) The elements across the periods show repeating patterns in chemical and physical properties. This is called periodicity.

   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.

   Why did Mendeleev put the elements in Group 1A in the same group?

   • The elements in 1A are all very reactive and form compounds in the same ratios with similar properties with other elements. Because of their similarities in their chemical properties, Mendeleev put these elements into the same group. Group 1A is also known as the alkali metals.

   What is Group 1A & Group 2A?

   • Group 1A is also known as the alkali metals. Although most metals tend to be very hard, these metals are actually soft and can be easily cut. Group 2A is also called the alkaline earth metals. Once again, because of their similarities in electron configurations, these elements have similar properties to each other.

   Should a 32-column periodic table have a split D-Block?

   • Reger et al. (2010, p. 295) write that “perhaps” the correct shape of the 32-column periodic table should feature a split d-block given the electron configurations of La and Ac, but that “we avoid these structures by splitting the f-block from the rest of the periodic table.

   What elements are in Group 3?

   • The periodic table appearing on the IUPAC web site (Fig. 1) depicts the first two elements of Group 3 as being scandium and yttrium. Below the box for yttrium is found one box for the lanthanoids and below that one box for the actinoids.

   How many interlocking arguments are there for lanthanum in Group 3?

   • Continuing the theme, a series of ten interlocking arguments, in the context of a chemistry-based periodic table, are presented in support of lanthanum in Group 3. In so doing, I seek to demonstrate a new way of thinking about this matter. The last of my ten arguments is recast as a twenty-word categorical philosophical (viewpoint-based) statement.

   Jun 23, 2021 · Groups and periods organize elements on the periodic table of the elements. A group is a vertical column down the periodic table, while a period is a horizontal row across the table. Both groups and periods reflect the organization of electrons in atoms.
