How many valence electrons are in ca
WebWhen we write the configuration we'll put all 20 electrons in orbitals around the nucleus of the Calcium atom. In writing the electron configuration for Calcium the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Calcium go in the 2s orbital. WebBoth atoms, which are in the alkali metal family, have only one electron in a valence s subshell outside a filled set of inner shells. (3.1.1) Li: [ He] 2 s 1 Na: [ Ne] 3 s 1 The alkaline earth metal magnesium (atomic number 12), with its 12 electrons in a [Ne]3 s2 configuration, is analogous to its family member beryllium, [He]2 s2.
