We already know what are elements in chemistry. In this article, we will learn about the most abundant element on earth and its atmosphere.\u00a0<\/p>\n\n\n\n

Some elements are found in abundance whereas some elements are almost rare on the Earth.<\/p>\n\n\n\n

Did you know that there are a total of 118 elements? (read What is an element in Chemistry with examples?<\/a>) And out of these, 94 elements occur naturally on earth, albeit in different concentrations.\u00a0<\/p>\n\n\n\n

But which element is present in the greatest abundance on the earth? Let\u2019s take a look.<\/p>\n\n\n\n

Iron:- It\u2019s the most abundant element on earth<\/strong>. (including the concentration in all three layers)<\/p>\n\n\n\n

The Earth weighs around 5.98 x 1024<\/sup> Kg. And that it is composed mostly of iron (32.1%), oxygen (30.1%), silicon (15.1%), magnesium (13.9%), sulfur (2.9%), nickel (1.8%), calcium (1.5%), and aluminium (1.4%, with the remaining 1.2% consisting of rare elements.<\/p>\n\n\n\n

However, individual earth layers have varying concentrations of the elements.<\/p>\n\n\n\n

(Quick refresher The earth consists of three layers-crust, mantle, and core.)<\/p>\n\n\n\n

Most abundant element on earth crust<\/h2>\n\n\n\n

The crust is the outermost layer of the Earth. It contains both oceans and landmasses.<\/p>\n\n\n\n

Oxygen-The Most Abundant Element in Earth\u2019s Crust<\/strong><\/p>\n\n\n\n

Oxygen constitutes about 46.6% of the mass of the earth\u2019s crust, making it the most abundant element in the earth\u2019s crust.<\/p>\n\n\n\n

It is most commonly found in combination with silicon and iron as silicate minerals and iron ore compounds respectively.<\/p>\n\n\n\n

Silicon-The Second-Most Abundant Element in Earth\u2019s Crust<\/strong><\/p>\n\n\n\n

Silicon makes up about 28% of the earth\u2019s crust by mass and is, therefore, the second most abundant element in the earth\u2019s crust.<\/p>\n\n\n\n

It is commonly found in combination with oxygen as silicate materials.<\/p>\n\n\n\n

Aluminum-The third-most common element in the Earth\u2019s crust<\/strong><\/p>\n\n\n\n

Aluminum comprises about 8.3% of the earth\u2019s crust by mass, making it the third most abundant element in the earth\u2019s crust.<\/p>\n\n\n\n

It is always found in combination with other elements.<\/p>\n\n\n\n

The common aluminum compounds found in the earth\u2019s crust are:-<\/p>\n\n\n\n

  1. Aluminium oxide<\/li>
  2. Aluminum hydroxide<\/li>
  3. Potassium aluminum sulfate<\/li><\/ol>\n\n\n\n

    Iron-The fourth most prevalent element in the Earth\u2019s crust<\/strong><\/p>\n\n\n\n

    Iron composes about 5.6% of the earth\u2019s crust by mass, making it the fourth most prevalent element in the earth\u2019s crust.<\/p>\n\n\n\n

    The common iron compounds found in the earth\u2019s crust are:-<\/p>\n\n\n\n

    1. Hematite<\/li>
    2. Magnetite<\/li>
    3. Siderite<\/li><\/ol>\n\n\n\n

      Calcium-The fifth most abundant element in the Earth\u2019s crust<\/strong><\/p>\n\n\n\n

      Calcium comprises about 4.2% of the earth\u2019s crust by mass, making it the fifth most abundant element in the earth\u2019s crust.<\/p>\n\n\n\n

      As with aluminum, calcium is highly reactive and is not found free in nature. It readily reacts with oxygen and water to form its compounds. The common calcium compounds in the earth\u2019s crust are:-<\/p>\n\n\n\n

      1. Calcium carbonate<\/li>
      2. Gypsum<\/li>
      3. Anhydrite<\/li>
      4. Fluorite<\/li>
      5. Apatite<\/li><\/ol>\n\n\n\n

        Other common elements in the Earth\u2019s crust:-<\/p>\n\n\n\n

        1. Sodium-Sixth most common element (2.5% of the earth\u2019s crust by mass)<\/li>
        2. Magnesium-Seventh most prevalent element (2.4% of the earth\u2019s crust by mass)<\/li>
        3. Potassium-Eighth most abundant element (2% of the earth\u2019s crust by mass)<\/li><\/ol>\n\n\n\n

          The most abundant element in the oceans<\/h2>\n\n\n\n

          The five most abundant elements in the ocean by mass are:- <\/p>\n\n\n\n

          1. Oxygen (85.84%)<\/li>
          2. Hydrogen (10.82%)<\/li>
          3. Chlorine (1.94%)<\/li>
          4. Sodium (1.08%)<\/li>
          5. Magnesium (0.13%)<\/li><\/ol>\n\n\n\n

            The Most Abundant Element In The Earth’s Mantle<\/h2>\n\n\n\n

            The mantle is the second layer of the earth. And unlike the earth\u2019s crust, the concentration of magnesium is way greater.<\/p>\n\n\n\n

            The most abundant elements, by mass, in the earth\u2019s mantle are as follows:<\/p>\n\n\n\n

            1. Oxygen 45%<\/li>
            2. Magnesium 23%<\/li>
            3. Silicon 22%<\/li>
            4. Iron 5.8%<\/li>
            5. Calcium 2.3%<\/li>
            6. Aluminum 2.2%<\/li>
            7. Sodium 0.3%<\/li>
            8. Potassium 0.3%<\/li><\/ol>\n\n\n\n

              The Most Abundant Element In The Earth’s Core<\/h2>\n\n\n\n

              The Earth’s core is the innermost layer. It is primarily composed of iron (88.8%). Other common elements:-<\/p>\n\n\n\n

              1. Nickel (5.8%)<\/li>
              2. Sulfur (4.5%)<\/li><\/ol>\n\n\n\n

                Most abundant element on earth atmosphere<\/h2>\n\n\n\n

                The most abundant element in the atmosphere by volume fraction is nitrogen (78.1%). Other more prevalent elements in the atmosphere:-<\/p>\n\n\n\n

                1. Oxygen (20.9%)<\/li>
                2. Argon (0.96%)<\/li><\/ol>\n\n\n\n
