For a cation to form, one or more electrons must be lost, typically pulled away by atoms with a stronger affinity for them. These minerals are ionically bonded and typically contain cations of alkali and alkaline earth ele ments (Na, K, and Ca). By convention, elements are organized in the periodic table, a structure that captures important patterns in their behavior.Devised by Russian chemist Dmitri Mendeleev (1834-1907) in 1869, the table places elements into columnsgroupsand rowsperiodsthat share certain properties.These properties determine an element's physical state at room temperaturegas, solid, or liquid .

In fact, for the alkali metals (the elements in Group 1), the ease of giving up an electron varies as follows: Cs > Rb > K > Na > Li. If a balanced atom gains one or more electrons, it will become a negatively charged anion. A cation has more protons than electrons, consequently giving it a net positive charge. Expert Answer 100% (1 rating) Answer , Cs will give up an electron most easily among all three. Which one do you think would fit best with a superhero story? Go on an element scavenger hunt! On the periodic table, what are elements from the 7A(17) group called? The Periodic Table The Periodic Table organizes the elements according to their properties.
