When ml can only equal 1‚ each energy level can have only 1 orientation so according to the exclusion principle only 2 electrons with opposite spins can be in each orbital. So in order to get to element 30 you would need to go all the way to the 6p orbitals. In other words‚ every two electrons would necessitate going to a new orbital. 1 | 1s1 | 11 | 1s2 2s2 2p2 3s2 3p2 4s1 | 21 | 1s2 2s2 2p2 3s2 3p2 4s2 3d2 4p2 5s2 4d2 5p1 | 2 | 1s2 | 12 | 1s2 2s2 2p2 3s2 3p2 4s2 | 22 | 1s2 2s2 2p2 3s2 3p2 4s2

COMMENTARY - REINDEER AND ENGINE This poem‚ "Reindeer and Engine" is by Josephine Jacobsen. It is set in a ’Finnish forest track’ where a reindeer is being chassed by a train. It flees from the light of the train as it ’runs’ forward trying to escape. This is a narrative poem because it tells a story from an omniscient point of view. It is written in four stanza’s each one telling a different part of the story. The first idea we come across is that of light. ’The great round eye’ in the first line

In The Belief Engine‚ James Alcock introduces two interesting components in our internal belief engine‚ the Critical-Thinking Unit‚ and the Memory Unit. These two corresponding items work hand and hand to help logical thinkers to understand the world around them through personally analyzing their own past without bias from the Emotional Response Unit‚ or any other conflicting counter-part. Critical thinking is not an innate ability. As mentioned in the article many of us are born with what Alcock

Atomic radii • Ingoing from top to bottom of a group‚ the outermost electrons are assigned to orbitals with increasingly higher values of the principal quantum number. The underlying electrons require space so the electrons of the outer shell is farther from the nucleus. • In a period‚ going across the period‚ a proton is added to each nucleus and an electron is added to each outer shell. In each‚ the effective nuclear charge increases slightly because the effect of each additional proton is more
