Answer:

The elements in the periodic table are arranged in order of increasing atomic number. All of these elements display several other trends and we can use the periodic law and table formation to predict their chemical, physical, and atomic properties. Understanding these trends is done by analyzing the elements electron configuration; all elements prefer an octet formation and will gain or lose electrons to form that stable configuration.

The location of elements in the periodic table are:

  • Magnesium-group 2 alkaline earth metal
  • Iron - 26th element, period 4 and group 8.
  • Sulfur - 16th element, period 3 and group 16.
  • Neon - present in group 18.

Write the physical properties of the given elements?

The physical properties of these elements are the following:

  • Magnesium: it is a good conductor of electricity, and electromotive metal.
  • Iron: it is a ductile, malleable, silver - gray metal.
  • Sulfur: tasteless, odorless, insoluble in water, pale yellow color.
  • Neon: chemically inactive, odorless inert gas.

Thus, the places of the elements in the periodic table are:

  • Magnesium-group 2 alkaline earth metal
  • Iron - 26th element, period 4 and group 8.
  • Sulfur - 16th element, period 3 and group 16.
  • Neon - present in group 18.
