An element, simply put, is afundamental unit of matter that cannot be easily broken down. It consists of a specific number of protons and variable neutrons and electrons. All of matter is made of these 118 elements, combined in various ratios and kept in different states, like solids. Depen...

Atomic-scale computer simulation has been used to study the thermally activated atomic transport of self-interstitial atoms (SIAs) in the form of planar clusters in pure Cu and f-Fe. There is strong evidence that such clusters are commonly formed in metals during irradiation with high-energy par...
Atomic Mass of Iron An element's atomic mass is equal to the sum of the individual particle masses of an atom. Atoms have three basic particles which include protons, neutrons, and electrons. The standard unit for measuring atomic mass is the Dalton (u). ...

SINCE our short account of the method of observing the Stark effect with a stabilised arc was written (see NATURE, March 31, p. 431), we have made experiments on about twenty different metals. With elements having a simple spectrum, as silver, copper, zi
Copper was the first metal to be worked by man, along with gold and meteoritic iron. This is because these metals were among the few that exist in theirnative state, meaning the relatively pure metal could be found in nature. The use of copper dates back more than 10,000 years. Otzi ...
