if it can't have full outer level, atoms likes to have half filled orbitals
these are slightlt more stable (less reactive) than other choices
positive ions are
smaller then corresponding neutral atoms because it lost one energy level (goes down a shell energy level, decreasing the size) positive char (p) hasnt changed but pulling on fewer electrons
ionization energy column trend
decreases down a column because electron is greater distance from nucleus, valence electrons are shielded from pull of nucleus by core electron
ionization energy exception trend
electron from full or 1/2 full sublevel more stable than trend so greater ionization energy
relative tendency of an atom to attract electrons to itself when it is chemically combined with another element
electronegativity upper right
increases to upper right (not noble gases) b/c less distance from nucleus to outer reacting electrons, shielding effect less so it does not affect reacting electron so increases at top of group; more protons in nucleus so more pull for outer electron as go across row to right
the energy change that accompanies the addition of an electron to a gaseous atom
electron affinity across a period
across a period inc to right because increased nuclear char (#p) but if stable will cause deviation
negative electron affinity means
more stable as is, does not want more electrons (must add E to force it to take that electron)
