(1) Why do transition metal ions possess a great tendency to form complexes? (2) The paramagnetic character in 3d-transition series elements increases up to Mn and decreases. View Solution Explain the following observations: (a) Azide ion (N3) react with 2− bromopentane thousand times ...
Why are halogens and alkali metals likely to form ions? What happens when metals combine with nonmetals? Why are ionic compounds electrically neutral? How does hydrogen show properties of both metals and nonmetals? When metals combine with nonmetals, what do the metallic atoms tend to do? Con...
The structures of pure metals are simple to describe since the atoms that form these metals can be thought of as identical perfect spheres. More specifically the metallic structure consists of 'aligned positive ions' (cations) in a "sea" of delocalized electrons. This means that the electrons ...
Transition metal atomsGround and low-lying excited statesNumerical Hartree-Fock approximationNumerical Hartree-Fock (NHF) calculations have been performed for 332 ground and low-lying excited states of the fifth period atoms Rb through Xe, with our special interest in the states arising from the 5 ...
Explain how a non-metal atom becomes negative. Explain why Zr4+ ion exists? Why do atoms hybridize? What causes atomic vibration? Why do hydrogen atoms emit or absorb only discrete amounts of energy? What determines if something is a strong or weak conductor? ...
Answer: Metals are an excellent conductor of electricity and heatbecause the atoms in the metals form a matrix through which outer electrons can move freely. Instead of orbiting their respective atoms, they form a sea of electrons that surround the positive nuclei of the interacting metal ions. ...
Why do atoms of the same group form ions of the same charge? (a) They have the same number of valence electrons (b) They have the same number of protons (c) They have the same number of electrons (d) They have the same number of valence ne...
Unlike elements in groups 1A-3A, which can form cations, and atoms in groups 7A-5A, which can form anions, noble gases generally do neither. Using neon as a specific example, explain why this is so. What can be said about the ions of atoms in the...
Explain why copper pairs do not scatter from positive lattice ions in a metal. Why does the potential inside a solid conductor not change? Explain why the transition metals have good thermal and electrical conductivities. Why is metal a good THERMAL conductor but plastic...
Why do atoms react to one another instead of fusing together completely? Why does a sodium street lamp give off a different color light than a neon light? What are some factors that influence the color of transition metal complexes? Why are ...
