SEC 1 Bonding Molecular Orbital Wave Properties of Electrons Standing wave vibrates in fixed location. ■ Wave function,w,mathematical description of size,shape,orientation. Amplitude may be positive or negative. Node:amplitude is zero. nodal plane nucleus represented by nucleus wave function (instantaneous picture) nodal plane
SEC 1 Bonding & Molecular Orbital Wave Properties of Electrons ◼ Standing wave vibrates in fixed location. ◼ Wave function, , mathematical description of size, shape, orientation. ◼ Amplitude may be positive or negative. ◼ Node: amplitude is zero
Wave Interactions Linear combination of atomic orbitals oon different atoms produce molecular orbitals oon the same atom give hybrid orbitals. Conservation of orbitals. Waves that are in phase add together. Amplitude increases. Waves that are out of phase cancel out
