Answer

Explanation:

Step1: Identify heavier element

Iron is heavier than hydrogen.

Step2: Draw iron atom

Iron (Fe) has atomic number 26. First shell has 2 electrons, second has 8, third has 14 and fourth has 2. Draw nucleus with 26 protons (P) and 30 neutrons (N) (average atomic mass of Fe is about 56, so 56 - 26 = 30 neutrons). Then draw 4 electron - shells with 2, 8, 14, 2 electrons respectively.

Answer:

  1. Elements are iron and hydrogen.
  2. Circle iron.
  3. Draw an atom with nucleus having 26 protons and 30 neutrons, and 4 electron - shells with 2, 8, 14, 2 electrons in order from innermost to outermost.
