When Na forms an ion it loses its outer electron to become Na+. Write the electron configuration for Na and Na+. What element does Na + 's electron configuration resemble (with respect to its electron arrangement) ? In general, which group's electron configuration do the alkali metals resemble when they form ions? (ie, lose an outer electron)

Joyce Warner · Answer 1

Na: 1s2 2s2 2p6 3s1

Na+: 1s2 2s2 2p6

Na + electronic configuration resemble that of Neon (1s2 2s2 2p6)

In general, the electronic configuration of alkali metals ions resemble that of the group zero (noble gas)
