The 3 least abundant elements are Francium (Fr), Astatine (At),and Plutonium (Pu). Francium and Astatine come from the decay of Thorium (Th) and Uranium (U), are much more abundant. At any one time in the entire earth's crust there is only 30 grams of Francium and 25 grams of Astatine. Plutonium is only found in Uranium minerals. The amount of Plutonium is microscopic. Here are the 3 least abundant elements.

The most common element in the earth's crust is oxygen.
Oxygen and silicon are the two most abundant elements in the Earth's crust. They make up about 75% of the Earth's crust by weight.
False. Elements abundant in the human body, such as oxygen, carbon, hydrogen, and nitrogen, are also abundant in the Earth's crust.
The two most common elements found in the Earth's continental crust are oxygen and silicon. Oxygen is the most abundant element, making up about 46.6% of the Earth's crust by weight, while silicon is the second most abundant, making up about 27.7%.
Igneous. Basalt is the most abundant in oceanic crust and granite is the most abundant in continental crust.
