I was studying about properties and behaviour of hydrogen and found that hydrogen is lightest element.It is so light that 1 litre of hydrogen at N.T.P weighs only 0.0980 grams.
The first statement that hydrogen is lightest element seems reasonable to me,but the data 1 litre of hydrogen at N.T.P weighs only 0.0980 grams has shocked me. Isn't it so so so light.
Hence,the question i m asking is why hydrogen is so so so light??
The reason behind it is not given in my book so i supposed to ask it here.I shall be very thankful iif someone of you give me a reasonable answer for it.
