For many years, scientists couldn’t figure out how atoms and molecules combined to make living things. Plants, fish, dinosaurs, and people are made of atoms and molecules, but they are put together in a more complicated way than the molecules in the primitive ocean. What’s more, living ...

How many atoms are estimated to be in the observable universe? It is estimated that there are around 1080 atoms in the observable universe. This number is derived from calculations based on the estimated number of galaxies, stars, and the average mass of matter in the universe. What is the...
When physicists at Princeton heard the news, they became a "stirred-up ant heap." Beyond the buzz of the discovery, other repercussions became quickly apparent: Not only did this event, called nuclear fission, create two smaller atoms, but breaking these powerful atomic bonds released a relative...
The pressure is high enough to force atoms of hydrogen to come together in nuclear fusion reactions — something we try to emulate here on Earth. Two atoms of hydrogen are combined to create helium-4 and energy in several steps: Two protons combine to form a deuterium atom (hydrogen atom ...
It may not be as hellish as Venus, but the fourth planet from the sun still isn't what most people would call hospitable. The atmosphere on Mars differs from Earth's in many ways, and most of them don't bode well for humans living there. Composed mostly of carbon dioxide (the gas ...
Gravitational energy is one that surrounds the earth. It is the energy that is consumed when we fall or when we ride uphill. 5. Nuclear Energy Consumption This type of energy gets saved inside tiny atoms that remain invisible. These atoms make up the entire universe. The fission reaction tha...
The letter “H” symbolically refers to the hydrogen atom, the number “2” refers to the number of hydrogen atoms in the molecule, and the letter “O” symbolically refers to the oxygen atom. However, when pupils increase their understanding of scientific phenomena, by “seeing” what is ...
To simulate the many-electron systems such as heavy atoms, multi-atomic molecules, and condensed matter, the semi-classical approximation should be combined with statistical one. Even the simplest Thomas–Fermi model [43,44] gives the intra-atomic electron density distribution, which is suitable as...
