You are watching: Which statement best describes the basis of the band theory of metallic bonding?
A).Electron gain enthalpy is the amount of energy released when an isolated gaseous atom accepts an added electron to develop the gaseous negative ion. So, once we talk about the noble gases , they have entirely filled shells so they have actually not any kind of area to place an extra electron in their valence orbital and so the electron is inserted in following higher energy level which requires a large energy to be offered and also so the electron acquire enthalpy is positive for noble gases.b).Alengthy a duration, the electron get enthalpy boosts and it becomes maximum negative in halogensbereason,they have actually the valance shell configuration ns2np5 which calls for just one electron to be steady and so they have stronger tendency to accept electron and so they have greatest negative electron acquire enthalpy.c).Electron gain enthalpy is not zero for Be, Mg ,N and P quite it has addressed worth as, Be has +66KJ/mol, Mg has actually +67KJ/mol, N has actually +31KJ/mol and also P has actually -74KJ /mol.d).Due to the smaller dimension of Fluorine atoms, they have comparatively larger electron-electron repulsion in 2p -sub shell so that the incoming electron is not embraced as quickly as in chlorine atoms and so, the electron acquire enthalpy of F is comparatively much less negative than that of Cl.
(C) Atomic orbitals overlap to form molecular orbitals in which the valence electrons of the atoms take a trip.
