WebAll the alkali metals—lithium, sodium, potassium, and so on—have only one electron in their valence shell. Because this one electron is likely to be far from the nucleus, it feels little attraction to the atom. The result: Alkali metals tend to lose this electron when they participate in reactions. These elements all “look” similar from ... WebIn a group, metallic properties increase and non-metallic properties decrease throughout the group. 4. Chemical reactivity: The chemical reactivity of an element can be clearly understood by studying the reaction of the element with oxygen and halogens. Elements combine with oxygen to form oxides.
