Thinking Flexibly
“Of all forms of mental activity, the most difficult to induce even in the minds of the young, who
may be presumed not to have lost their flexibility, is the art of handling the same bundle of data
as before, but placing them in a new system of relations with one another by giving them a
different framework, all of which virtually means putting on a different kind of thinking-cap for the
moment.
It is easy to teach anybody a new fact...but it needs light from heaven above to enable a teacher
to break the old framework in which the student is accustomed to seeing.”
Elements want to become through chemical reactions, because of this reason metals give away their valance electrons and non-metals gain electrons to get to a stable number of 8 electrons on the valance energy level.
chemical reactions of metal and non-metal depend on valence electrons in each atom, Valence electrons are the outermost electrons on the last energy level of an atom. Valence electrons for the same as the group A elements are the same as the group number.
Example: Li is in group 1A, it has one valence electron. In an atom electron have different energies and occupy different energy levels and sublevels. Each energy has sublevels. Always think of how you might be able to do the same things but in different ways.
