What 5 elements make up 99% of the human body?
It is thus no wonder that 99% of the atoms in the human body come from six elements: Hydrogen (62.9%), oxygen (almost 24%), carbon (nearly 12%), nitrogen (nearly 0.6%), calcium (0.24%) and phosphorus (0.14%). Calcium is on the list as it is essential for our skeleton, which contains 99% of the calcium in our body.
What elements make up a human?
The four most abundant elements in the human body – hydrogen, oxygen, carbon and nitrogen – account for more than 99 per cent of the atoms inside you. They are found throughout your body, mostly as water but also as components of biomolecules such as proteins, fats, DNA and carbohydrates.
Which element is maximum in human body?
Oxygen is the most abundant element in the human body accounting for approximately 65% of a person’s mass. Each water molecule consists of two hydrogen atoms bonded to one oxygen atom, but the mass of each oxygen atom is much higher than the combined mass of the hydrogen.
Is there gold in our body?
An adult human body weighing 70 kg contains about 0.2 milligrams of gold. It’s been found that the element plays an important health function, helping to maintain our joints, as well as facilitating the transmittal of electrical signals throughout the body.
Which part of human body contains most gold?

What elements make up 99% of the mass of the body?
Six elements account for 99% of the mass of the human body. The acronym CHNOPS may be used to help remember the six key chemical elements that are used in biological molecules. C is carbon, H is hydrogen, N is nitrogen, O is oxygen, P is phosphorus, and S is sulfur.
What is the second most abundant element in human body?
Carbon is the second most abundant element in the human body, accounting for 18% of body weight. All organic molecules (fats, proteins, carbohydrates, nucleic acids) contain carbon.
How many elements make up 96% of our body weight?
Elements are listed in order of decreasing abundance, with the most common element (by mass) listed first. Approximately 96% of body weight consists of only four elements: oxygen, carbon, hydrogen, and nitrogen.
