what is the distance between atoms in a solid
Atomic spacing The spacing between atoms in most ordered solids is on the order of a few ångströms (a few tenths of a nanometer). In very low density gasses (for example, in outer space) the average distance between atoms can be as large as a meter.
Rate equation k is the first order rate constant, which has units of 1/s or sâˆ’1.
Isotope Isotopes are atoms of the same element having the same numbers of protons (atomic number), but different numbers of neutrons. They have same chemical properties due to the same electron configuration, but different physical properties.[citation needed]
Limit of a function (the Dirichlet function) has no limit at any x-coordinate.
