many labs are late again!

Check iPass only two labs handed in out of the whole class

Write your lab tonight it is way over due! one week late!

Test tuesday

Electron configuration, lewis dot, valence electrons, charges of elements, Hund's rule, Aufbau principle, Pauli Exclusion principle, periodic trends, periods and groups, reactivity and periodicity lab, S block elements, P block elements and D block elements, names of groups.

out monday assignment for class

For each of the combinations- which has the greatest Ionization energy, electron affinity, atomic radius, electronegativity? Na vz K; Li vs F; C vs Si; B vs Al; oxygen vs Nitrogen; H vs He; Mg vs Ca; Li vs Fr; Ne vs Xe;

Great job on electron configurations!
