(iii) A measurement of the number of atoms in 12g (i.e. 0.012kg) of carbon 12 has two sources of uncertainty [7]: first, the uncertainty in the mass of the carbon-12 atom measured in terms of the kilogram; and second, the Nettet(Ex: if a student predicts that an atom is 1/1 millionth of a meter, show them how to write this as 1.0 x 10 –6) Although there may be some students who already have a good idea of just how small an atom is, many students struggle when trying to …

NettetAn atom is the smallest unit of ordinary matter. Atoms are around 100 picometers (10 −10 m or 0.1 nm) across. Usually, we use 1 angstrom (1Å = 10 −10 m) for the size of an atom. [In this image] An illustration of the helium atom, depicting the nucleus (pink) and the electron cloud distribution (black). The black bar is one angstrom. NettetIt’s difficult to imagine just how small that is, so here are some examples: A sheet of paper is about 100,000 nanometers thick; A strand of human DNA is 2.5 nanometers in diameter; There are 25,400,000 …
