November 12. The electron affinity is the energy released when an electron is added to a neutral atom to make a 1- anion. The table below shows the electron affinities for the 2nd period (row) elements. The value reported is the amount of energy released when an electron is added to a neutral atom. If no energy is released the anion is not stable and that is reported. Explain the overall trend of electron affinity increasing as you move left...

Classify each statement about effective nuclear charge, Zeff, as true or false Effective nuclear charge is dependent on the number of electrons present in the atom In a Be atom, a 1s electron has a greater Zeff than a 2s electron Across a period, as Zeff increases atomic size decreases Electrons in a p orbital are more effective than those in other orbitals at shielding other electrons from the nuclear charge A 1s electron in a Be atom has a...
