WitrynaThe only alkali metal to react with atmospheric nitrogen is lithium. Heavier alkali metals react with graphite to form graphite intercalation compounds, substances in which metal atoms are inserted between the sheets of carbon atoms. With heavier group 14 elements, alkali metals react to give polyatomic anions with three-dimensional cage ... WitrynaLi, Na, K, Rb, and Cs are all group IA elements, also known as the alkali metals. The seventh member of the group, francium (Fr) is radioactive and so rare that only 20 atoms of Fr may exist on Earth at any given moment [1]. The term alkali is derived from an Arabic word meaning “ashes.”.

WitrynaThe Group 7A elements have seven valence electrons in their highest-energy orbitals ( ns2np5 ). This is one electron away from having a full octet of eight electrons, so these elements tend to form anions having -1 charges, known as halides : fluoride, F -; chloride, Cl -, bromide, Br -, and iodide, I - .

WitrynaSo that's one way to number your groups. There is another way to number your groups, and that would be to say that group 1 is group 1A, group 2 is group 2A. And then kind of ignoring groups 3 through 12, continue on with your numbering system. So 1A, 2A-- that would make this group 3A, group 4A, group five 5A, group 6A, 7A, and finally 8A. WitrynaIn the alkali group, as we go down the group we have elements Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs) and Francium (Fr). Several physical properties of these elements are compared in Table 7.7.1. These elements have all only one electron in their outermost shells.
