Mišo Zozoli. Josip Dajčman. Atomi (trans. The Atoms) were a Yugoslav rock band formed in Zagreb in 1961. They were one of the pioneers of the Yugoslav rock scene . Heavily influenced by The Shadows, Atomi were arguably the first instrumental rock band in Yugoslavia. The band gained local popularity, which gave them an opportunity to become ...
The periodic table is a tabular arrangement of the chemical elements, organized by their atomic number, electron configuration, and chemical properties. It is a useful tool for understanding the patterns and trends of the elements and their interactions. Learn more about the history, structure, and significance of the periodic table on Wikipedia.
List of chemical elements. 118 chemical elements have been identified and named officially by IUPAC. A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z ). [ 1]
Indium. body-centered tetragonal ( tI2) Indium is a chemical element; it has symbol In and atomic number 49. It is a silvery-white post-transition metal and one of the softest elements. Chemically, indium is similar to gallium and thallium, and its properties are largely intermediate between the two. [ 10]
This unit is defined as a twelfth of the mass of a free neutral atom of carbon-12, which is approximately 1.66 × 10 −27 kg. [61] Hydrogen-1 (the lightest isotope of hydrogen which is also the nuclide with the lowest mass) has an atomic weight of 1.007825 Da. [ 62 ] The value of this number is called the atomic mass .
The Turabay dynasty was a family of Bedouin emirs who governed the district of Lajjun in northern Palestine during Ottoman rule in the 16th–17th centuries. The family's forebears had served as chiefs of Jezreel Valley during Mamluk rule in the late 15th century. During the Ottoman conquest of the region in 1516–1517, the family aided ...
The atomic radius of a chemical element is the distance from the center of the nucleus to the outermost shell of an electron. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. Depending on the definition, the term may apply only to isolated atoms, or also to atoms in ...
Atomism (from Greek ἄτομον, atomon, i.e. "uncuttable, indivisible") [ 1][ 2][ 3] is a natural philosophy proposing that the physical universe is composed of fundamental indivisible components known as atoms . References to the concept of atomism and its atoms appeared in both ancient Greek and ancient Indian philosophical traditions.
