    en.wikipedia.org/wiki/Period_2_element

    A period 2 element is one of the chemical elements in the second row (or period) of the periodic table of the chemical elements.The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behavior of the elements as their atomic number increases; a new row is started when chemical behavior begins to repeat, creating columns of elements with similar properties.

    Upon room temperature action with sodium chlorite, Na 2 H 2 P 2 O 6 is formed. [17] Red phosphorus can be used as an elemental photocatalyst for hydrogen formation from the water. [18] [7] It has also been researched as a sodium ion battery anode. [19] [2]

    en.wikipedia.org/wiki/Graphene

    Graphene exhibits high electron mobility at room temperature, with values reported in excess of 15 000 cm 2 ⋅V −1 ⋅s −1. [2] Hole and electron mobilities are nearly identical. [ 73 ] The mobility is independent of temperature between 10 K and 100 K , [ 32 ] [ 79 ] [ 80 ] showing minimal change even at room temperature (300 K), [ 2 ...

    A change in pH by 0.1 represents a 26% increase in hydrogen ion concentration in the world's oceans (the pH scale is logarithmic, so a change of one in pH units is equivalent to a tenfold change in hydrogen ion concentration). Sea-surface pH and carbonate saturation states vary depending on ocean depth and location.
