Full Answer

Iron is one of the most abundant metals on Earth, comprising 5.6 percent of the crust. Iron alloys with carbon to make steel, and it is easily alloyed with many other metals, such as tungsten and chromium. Iron is essential to both photosynthesis and respiration because of its affinity for oxygen.

  • Q:

    What is the modern periodic law?

    A:

    Periodic law, also known as Mendeleev's law, is the concept that the chemical and physical properties of elements are based on an element's atomic weight when arranged by increasing periodic atomic number. Periodic law was first developed in 1869 when Dimitri Mendeleev and Lothar Meyer each developed a periodic table on their own and noticed similarities in elements with comparable atomic masses. Both men organized the elements by their masses and noticed certain properties recur periodically.

  • Q:

    What determines the chemical properties of an element?

    A:

    The chemical properties of an element are determined by the electrons in the partly filled outermost shell. This shell is referred to as the valence shell. There are one or more subshells in each shell, and each subshell is made up of one or more atomic orbitals.

  • Q:

    What two properties are the modern periodic table based on?

    A:

    The modern periodic table is based upon the atomic number and the physical properties of each element. The periods, or rows, are arranged by increasing atomic number. Each column, or group, of elements has similar physical properties.
