Storlek atom The atomic radius of a chemical element is a measure of the size of its atom, usually the mean or typical distance from the center of the nucleus to the outermost isolated electron. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. 1 vad är en atom enkel förklaring 2 10 −27 kg. Den lättaste atomen är väte, som väger cirka 1 u, vilket innebär att det går nära 6·10 23 väteatomer på ett gram väte. 3 förklara atom för barn 4 Size of atoms. Atoms have a radius of about nm (nanometres), or metres (1 × m). The nucleus of an atom is less than \ (\frac {1} {10,}\) the size of an atom. Isotopes. 5 Here are some typical atomic diameters: The diameters are slightly different, but are all about m. The size of these atoms is said to have an order of magnitude of To find the order of. 6 A convenient unit of length for measuring nuclear sizes is the femtometre (fm), which equals 10 −15 metre. The diameter of a nucleus depends on the number of particles it contains and ranges from about 4 fm for a light nucleus such as carbon to 15 fm for a heavy nucleus such as lead. 7 hur är en atom uppbyggd 8 Atomradien är ett mått på storleken av atomer. 9 Atomstorleken beror mest av hur många elektroner som en atom har. 10 How Small Is An Atom?
