Alkali metals typically lose one electron to become positively charged ions. This results in a full outer electron shell and a more stable electron configuration.
Group 1 elements have 1 electron on their outer shell because they belong to the alkali metal group, which has one electron in their outermost energy level. This configuration makes them highly reactive as they readily lose their outer electron to form a stable 1+ cation.
False. Alkali metals lose one electron to form a stable electron configuration with a full outer shell of electrons, which is the stable electron configuration for these elements.
Alkali metals have 1 electron in their outer shell, which makes them highly reactive. They easily lose this electron to form positively charged ions, making them good reducing agents. This electron configuration and reactivity are key factors influencing the properties of alkali metals.
When alkali metals react with other elements, the electrons in the outer shell of the alkali metal are transferred to the other element (usually a nonmetal). This transfer of electrons results in the formation of an ionic bond between the alkali metal cation and the nonmetal anion, creating a stable compound.
