Reactivity of group 1 elements
WebThe reactivity of Group 1 elements increases as you go down the group because: the atoms get larger the outer electron gets further from the nucleus the attraction between the nucleus and outer electron gets weaker – so the electron is more easily lost WebSep 5, 2024 · Reactivity of Group 1 Elements The reactivity of alkali metals increases from the top to the bottom of the group, so lithium (Li) is the least reactive alkali metal and francium (Fr) is the most reactive. Because alkali metals are so reactive, they are found in nature only in combination with other elements.

WebThe reactivity of the group 1 metals increases as you go down the group; When a group 1 element reacts, its atoms only need to lose the 1 electron in the outer shell When this happens, 1+ ions are formed; The next shell down automatically becomes the outermost shell and since it is already full, a group 1 atom obtains noble gas configuration
WebAs alkali metals are the most reactive group of metals in the periodic table, each of these metals is capable of reacting with different elements to produce different results. Following chemical equations demonstrate …
