The space where the element lies (in correspondence with it's own "block") is the number on the exponent.
EXAMPLE: Carbon is second on it's block, it electronic configuration is 1s^2,2s^2,2p^2 F is fifth on it's block, it electronic configuration is 1s^2,2s^2,2p^5
The relationship between where elements is located in a block and super scripted value appearing at the end of the electronic configuration is that it gives information on the group the element exist in each block.
Explanation:
Blocks in the periodic table are divided as S, P, D AND F blocks. Representing elements with a electronic configuration gives information on the block that the elements falls on . For example Sodium and fluorine configurations are as follows ;
Sodium → 1s²2s²2p∧6 3s∧1
flourine → 1s²2s²2p∧5
The outer shell that ends the configuration determines the block it belongs. In this case sodium belongs to the s block while fluorine belongs to the p blocks. Then the super scripted value which is 1 for sodium depict it belong to group 1 of the s blocks. The super scripted value for fluorine which is 5 shows the element belongs to group 5 in the p blocks.
Light energy is turned into chemical energy when <span>when a photochemically excited special chlorophyll molecule of the photosynthetic reaction center loses an electron, undergoing an oxidation reaction.
The reason we cannot breath liquid water is because the oxygen used to make the water is bound to two hydrogen atoms and we cannot breath the resulting liquid
