1 de nov. de 2011 · The origin of life on Earth is still largely a mystery. The six essential elements of life possess some unique chemical properties that give them the ability to interact in a manner that is conducive to life as we know it. And yet, it does not mean that other elements could not do that job.
The four elements common to all living organisms are oxygen (O), carbon (C), hydrogen (H), and nitrogen (N), which together make up about 96% of the human body. In the nonliving world, elements are found in different proportions, and some elements common to living organisms are relatively rare on the earth as a whole.
- Thanks very much to everyone who noticed this problem and upvoted or commented on it. You're absolutely right that there is no meaningful way to cl...
- There are several forces at work inside the nuclei of atoms. The electromagnetic force of the protons wants to push them away from each other. Fusi...
- Molecules are made up of two or more atoms.
- Since electrons have like charges,they repel each other (much like a magnet).This results in our idea of solidity.
- How can atoms form a computer or an Egyptian pyramid or a novel? These are examples of what is known as an emergent property -- a property possesse...
- Exactly! It sounds surprising (I couldn't believe it when I first learned about it), but it's true.
- Imagine a stack of books, the atoms of the books aren't able to pass through each other because of the electron clouds that surround their nucleus....
- Water is not an element but a molecule but it is the most common molecule in our bodies. Oxygen is the most common element _by mass_ (43% of all we...
- Proton, by very little, is smaller.
