Calculate the de Broglie wavelength of a 143 g baseball

Solution 53EStep 1 2 6a)The electronic configuration of Ne is [He]2s 2p .The equation for ionization energy of Ne isNe (g) Ne +(g)+e-For the atom Ne, ionization energy is the energy required to remove an electron from theoutermost p electron of the gaseous atom .Electron is getting removed from an octetconfiguration.Hence sign of I.E will be positive. 2 5The electronic configuration of F is [He]2s 2p .The equation corresponding to gain of electronsis - -F (g) F (g)Thus if F gets an electron it can attain the stable noble gas configuration of Neon.Since noble gasconfigurations are always stable,greater will be the tendency to attain that configuration.Thuselectron affinity will be negative since energy is released during the process.
