Carbon, Helium, Oxygen
=========================
Mine are Hydrogen (in water), Oxygen (in water and air),
and Nitrogen (in air). Helium is not abundant on Earth at all.
Elements 1 and 3 are hydrogen and oxygen, respectively. When combined, they form water, which is the most common substance in the body.
The three most common elements in magnets are iron, nickel, and cobalt. These elements are known for their magnetic properties and are often used in various types of magnets.
Elements listed in the periodic table of elements are neutral; they do not have a charge. When they undergo chemical reactions they may become charged ions. There is no single most common charge for ions, but the most common are -1, -2, -3, +1, +2 and +3.
The three most common elements in Earth's atmosphere are nitrogen, oxygen, and argon. Nitrogen makes up about 78%, oxygen about 21%, and argon about 0.93% of the atmosphere.
The transition metals are the most common, and are found in the middle (groups 3-12) of the periodic table.

The most common ion of phosphorus is the phosphate ion, which has a charge of -3 (PO4^3-).
Oxygen and hydrogen
The four most common elements in living matter are carbon, hydrogen, oxygen, and nitrogen. Their valences are 4, 1, 2, and 3 respectively.
The three most common elements in the Earth's crust are oxygen, silicon, and aluminum.
The most common first languages in the world are Mandarin Chinese, Spanish, and English.
The transition metals are the most common, and are found in the middle (groups 3-12) of the Periodic Table.
The most common charge for phosphorus is -3, as it typically forms an anion by gaining three electrons to achieve a stable electron configuration.
The eight most common elements in the earths continental crust are; 1. Oxygen. 2. Silicon. 3. Aluminium. 4. Iron. 5. Calsium. 6. Sodium. 7. Potassium. 8. Magnesium.
