While these materials hold many interesting properties, scientists have long wanted to probe thin 2D metals. Now, researchers ...

Photo: Niels Bohr's research notes for his new atomic theory Rutherford's find came from a very strange experience. Everyone at that time imagined the atom as a "plum pudding." That is ...

independently of any atomic model:—(i) Three distinct regions of intra-atomic electrons exist, the number of which (say P, Q, R) may be calculated for each atom from the periodic system ...

In 1913, Niels Bohr revised Rutherford's model by suggesting that the ... However, there was still a difference between the atomic number of the atom and the atomic mass. Bohr and other scientists ...

A new reagent has moved carbon-atom transfer out of the chemical flatlands, allowing chemists to place a single carbon atom so that it makes bonds to four different substituents. The reagent makes ...

But they also performed density functional theory calculations ... hoping to push the approach to identify atomic species, to distinguish a carbon atom from an oxygen or a nitrogen or a sulfur ...
