Periodic table – Group 1 The alkali metals have a silvery, shiny surface when they are first cut. However, this goes dull very quickly as the metals reacts with the oxygen in the air. e.g. sodium + oxygen sodium oxide 4Na(s) + O2(g) 2Na2O(s) Lithium, sodium and pota...
We find that several putative sequence motifs [16] are significantly over-represented in the genes detected as periodically expressed (see Table 3). For instance, genes involved in DNA metabolism, morphogenetic activities and organization of chromosome structure contain some of these motifs. Furthermore...
For example, as you move across a row, elements go from metallic to less metallic. When you finish a row, the next row repeats those properties. Just like the seasons repeat themselves year after year. The periodic table also has COLUMNS. They are called: MORE about the P.T. ! What a...
