atom ion collisionssemi classical theory/ A3440 Elastic scattering of atoms and molecules A3450 Inelastic scattering of atoms and moleculesThe wavelengths associated with the motion of atoms and molecules at ordinary temperatures are short compared with the effective range of interaction between them. ...
Which atom is most likely to form a 2+ ion? (a) Zn. (b) Al. (c) S. (d) Na. (e) N. (f) Cannot be determined. Electronic configuration: The electronic configuration refers to the arrangement of the electrons of an atom or molecule in...
Electron affinity is the enthalpy change when a mole of electrons is added to a mole of neutral atoms (in the gaseous phase). This will form a negative ion - an anion. Electron Gain Enthalpy When electrons are introduced in...

Molecular iron maidens' structures are noted for the distinctive ultra-short interactions between the apical hydrogen atom, or its small substituent, and the benzene ring's surface. High steric hindrance is a commonly cited consequence of the forced ultra-short X contact in iron maiden molecules, ...
The geometry ion which hs no d electrons in the central metal atom is : [Atomic number Cr=24,Mn=25,Fe=26,Co=27] A[MnO4]− B[Co(NH3)6]3+ C[Fe(CN)6]3− D[Cr(H2O)6]3+Submit The geometry ion which hs no d electrons in the central metal atom is : [Atomic number Cr=24...
3. Defining Homo-leptic Complexes: Complexes in which the metal atom or ion is linked to only one type of ligand are called homo-leptic complexes. For example, if a metal ion is coordinated with six cyanide ions (CN⁻), it is a homo-leptic complex. Hint: The prefix "homo-" means...
An anion is formed when an electron is added to the valence shell of an atom. The anion has a net negative charge in it. In anion the extra electron added occupies more space and maximizes the shielding. Anions will have larger size compared to cation...
In order to avoid racemisation, build up of the peptide-like oligomer in the direction of C-terminus to N-terminus is recommended, if amino acids are present. In this case, the first module already carries a terminal group; if amino acids are present, this terminal group may be any ...
