A nanometer is the size of about 10 hydrogen atoms laid side by side
A nanometer is the size of around 5 atoms placed end to end
Atoms are in constant flux in the human body --- every year over 98% of atoms in your body are replaced
The atom is represented by a mere 92 unique naturally occurring elements like the 26 letters of our alphabet encompasses our communicative existence
A 52 card deck has more permutations than there are atoms in our Galaxy
The atom is mostly empty space --- if it were the size of a football stadium, the nucleus be the size of a small marble on the 50-yard line
Atoms are so tiny that a speck of dust is half way between its size and the size of the earth
Atoms have a lot of empty space --- Remove all the empty space in the atoms of all humans on earth and we could fit into an apple
atoms are small --- you'd need 2 million hydrogen atoms to cover the period at the end of this sentence.
If an atom were the size of the Earth, the proton at its center would be about 600 feet across
Atoms are largely empty space --- If you took out all the empty space in our atoms, the human race could fit in the volume of a sugar cube
Atoms are small --- there are 8 times as many atoms in a teaspoonful of water as there are teaspoonfuls of water in the Atlantic ocean
A nucleus is small --- if an atom were the size of a football stadium, the nucleus would be the size of a marble surrounded by vast regions of empty space
Atoms are so tiny that a sheet of paper is a million atoms thick
If an apple were blown up to the size of the earth, an atom in that apple would be the size of the original apple
If helium atoms were the size of a period [.] then gerbils would be the size of the earth
Atoms are different sizes -- the largest (cesium) is roughly nine times bigger than the smallest (helium)
An atoms thickness, compared to a piece of paper, is like comparing that same piece of paper's thickness to a 30 story building (328 feet)
Atoms are so tiny that an atom compared to a small person is similar in size to that small person compared to the sun
One second is technically the duration of 9,192,631,770 oscillations of a Caesium 133 atom's outermost electron.
