As we go down the group, the atom gets bigger. The bigger the atom, the further away the last electron. Therefore, the attraction between the nucleus and the last electron gets weaker. This makes it easier for the atom to give up the electron which increases its reactivity.

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 … WebSo, the metallic properties of elements tends to decrease across a period and increase down a group. The fact that the metallic elements are found on the left side of the periodic table offers an important clue to the nature of how they bond together to form solids. These elements all possess low electronegativities and readily form positive ions.

WebWe would like to show you a description here but the site won’t allow us. WebThe most active metals are so reactive that they readily combine with the O 2 and H 2 O vapor in the atmosphere and are therefore stored under an inert liquid, such as mineral oil.
