when atoms react, they often lose, gain, or share electrons to form a more stable version of themselves. for example, alkali met
AfilCa [17]

The electron configuration of alkali metals would then resemble those of group 17 of the periodic table in the compounds they form.

<h3></h3><h3>What is periodic table?</h3>

Periodic table is defined as a tabular approach of showing the items so that they appear in the same vertical column or group when their attributes are similar. Phosphorus is the oldest chemical element, and hassium is the newest. Please take note that, unlike in the Periodic system, the elements do not exhibit their natural relationships with one another.

The elements that make up group 17 of the periodic table are the halogens. They are nonmetals that are reactive, such as iodine, bromine, chlorine, and fluorine. Halogens are non-metals that are very reactive. These substances share a lot of characteristics with one another.

Thus, the electron configuration of alkali metals would then resemble those of group 17 of the periodic table in the compounds they form.
