WebElectron affinity of Boron is 26.7 kJ/mol. In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as: the change in energy (in kJ/mole) of a neutral atom or molecule (in the gaseous phase) when an electron is added to the atom to form a negative ion. X + e– → X– + energy Affinity = – ∆H. WebTrigonometric Periodicity Identities. The period of a function is the smallest amount it can be shifted while remaining the same function. In more formal terms, it is the smallest p p such that f (n+p)=f (n) f (n+p) = f (n) for all n n.
