It takes less energy to remove the second electron from calcium compared with the first because calcium wants to have eight electrons in its outer shell (and thus have a noble gas configuration. one or more electrons are transferred from metals to nonmetals, which form negative and positive ions; the electrical attraction between opposite charges is called an *ionic bond*. The numbers are the same; the signs are opposite. They get smaller, just like the atoms do. Chem., 1981, 93(1), p 44-63, in German; TR: Angew. (b) An ionic compound always has at least one metal. The International System of Units (SI) defines the second as the duration of 9,192,631,770 cycles at the microwave frequency of the spectral line corresponding to the transition between two hyperfine energy levels of the ground state of caesium-133.
