atom- (physics and chemistry) the smallest component of an element having the chemical properties of the element allotrope- a structurally different form of an element; "graphite and diamond are allotropes of carbon" transuranic element- any element having an atomic number greater than 92 (which ...

E.g. Hydrogen atom has three isotopes namely protium, deuterium, and tritium. The chemical properties of isotopes of an atom are similar but their physical properties are different.IsobarsAtoms of different elements with different atomic numbers, which have the same mass number, are known as iso...
These may be C1 atoms and, of the remaining 7 available surrounded by: for metal-metal bonding, 6 are considered to be in bonding orbitals and 1 in a nonbonding (a) Four similar units, with each of which a orbital. This accounts for the magnetic moment halogen atom is shared, ...
Hydroboration is regiospecific, the (LiBH4) and polyethers (NaBb). They can be boron showing preferential attachment to the least prepared by direct reaction of MH with either substituted C atom (anti-Markovnikov). This B2H6 or BX3 at room temperature though the finds ready interpretation in ...

is called the “donor lustrous and deformable and have high atom”. This type of bonding has already been electrical and thermal conductivities. In discussed (p. 198) and is exemplified by the addition, their melting and boiling points addition compounds formed by the trihalides tend to be ...
Some of the challenges involved in the study of the short-lived isotopes of the transactinides which can only be produced an “atom-at-a-time” are considered, and the types of experiments are discussed. Elements 104 and 105 behave as members of groups 4 and 5, as expected. However, dev...
