What stands for hydrogen on Pi chart

Answer 1

The term "Pi chart" is commonly known as a pie chart, which is a circular graph divided into sectors to represent the proportion of different categories or variables in a data set.

In the context of chemistry, hydrogen is typically represented by the symbol "H" on the periodic table and in chemical equations. However, in a pie chart, the actual representation or symbol for hydrogen may not be shown, as pie charts typically depict proportions or percentages rather than specific elements. Instead, the hydrogen data would be represented by a specific sector or slice of the pie chart.
