Study Notes

Periodic Table and Element Groups

  • Periodicity refers to the repeating patterns observed in the properties of elements across the periodic table.
  • Periodic Law states that the physical and chemical properties of elements are periodic functions of their atomic numbers.
  • Steel is an alloy made by combining iron and carbon.
  • Lanthanides are rare earth elements numbered from 57 to 71 in the periodic table.
  • Dmitri Mendeleev developed the first periodic table, organizing elements by atomic weight.
  • The periodic table contains 18 groups, which categorize elements based on similar properties.
  • Noble gases, found in group 18, are characterized by their lack of reactivity.
  • The periodic table consists of 7 periods, indicating the number of rows in the table.
  • Argon was the first noble gas discovered.
  • Alkali metals, located in group 1, are the most reactive metals.
  • Nonmetals are found on the right side of the periodic table and are poor conductors of heat and electricity.
  • Examples of metalloids include Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, and Polonium; they possess properties of both metals and nonmetals.
  • Metals, located on the left side of the periodic table, are good conductors of heat and electricity.
  • Henry Moseley created the modern periodic table, which is arranged by atomic number rather than atomic weight.
  • Halogens, found in group 17, are known as salt formers.
  • Valence electrons are located in the outermost shell of an atom and play a key role in chemical bonding.
  • The two elements that remain liquid at room temperature are Mercury and Bromine.
  • Main group elements comprise the elements from the s and p blocks of the periodic table.
  • Alkaline earth elements, found in group 2, possess two valence electrons.
  • Actinides are radioactive elements numbered from 89 to 103.
  • Transitional elements combine with oxygen to form various oxides.
  • The Oxygen family, known as chalcogens, includes elements that support combustion.
  • The Boron family consists of all metals and one metalloid, including aluminum.
  • The Nitrogen family is noted for containing nitrogen, the most abundant element in the atmosphere, also known as the pnicogen family.
  • The Carbon family features elements that are fundamental to organic compounds, supporting life forms.
