What are the 25 elements essential to life?
About 25 elements are essential to life (Figure 4-1). Four of these elements—oxygen (O), carbon (C), hydrogen (H), and nitrogen (N)—make up about 96 percent of the living matter in your body. Calcium (Ca), phosphorus (P), potassium (K), sulfur (S), and a few other elements account for most of the remaining 4 percent.
What is the lightest element on earth?
HydrogenHydrogen is the lightest element. Dihydrogen, H2, is a colorless, odorless, tasteless gas. The properties of hydrogen are summarized in Table 11.1.

What are the 10 most common elements on earth?
The mass-abundance of the nine most abundant elements in the Earth’s crust is approximately: oxygen 46%, silicon 28%, aluminum 8.3%, iron 5.6%, calcium 4.2%, sodium 2.5%, magnesium 2.4%, potassium 2.0%, and titanium 0.61%.
What’s the most useful element?
carbonLife demands a huge variety of molecules, with chains and rings and branches and cages—tricks that iron rarely attempts. And so we are left with carbon, the most versatile, most adaptable, most useful element of all. Carbon is the element of life.
Why is lithium so rare?
Because of its relative nuclear instability, lithium is less common in the solar system than 25 of the first 32 chemical elements even though its nuclei are very light: it is an exception to the trend that heavier nuclei are less common.
What are the top 10 most abundant elements in the human body?
Oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus are the most abundant elements found in the human body, followed by potassium, sulfur, sodium, chlorine, and magnesium.

What is the most abundant thing on earth?
Pelagibacter ubique is often cited as the most common organism ever: it’s a third of all the single-celled organisms in the ocean.
Why is oxygen so common in the universe?
Oxygen is the third most abundant element in the universe (after hydrogen and helium). It is therefore thought to be an important constituent of the clouds of gas and dust from which new stars and their planets develop.
