+!. The lakali metals are Li, Na K etc in group 1 with an electronic configuration with just ns1 as the outer shell.
Alkali metals generally form cations by losing their outermost electron to achieve a stable electron configuration.
Group 2, alkali earth metals.
Alkali metals forn cations with the chrage +1.
Cations are positively charged ions that can be formed by both metals and non-metals. However, cations are more commonly associated with metals because metals tend to lose electrons to form positive ions.
When group 1A elements form ions, they form cations with a +1 charge.
Cations are typically found on the left side and in the center of the periodic table. They are formed by metals that lose electrons, resulting in a positive charge. Groups 1 (alkali metals) and 2 (alkaline earth metals) are common sources of cations, as well as transition metals in the center. Nonmetals, located on the right side, generally form anions instead.
Your Alkali Metals are those elements on the leftmost column of the periodic table (except for Hydrogen). Lithium (Li), Sodium (Na), Potassium (K), Rubidium, Cesium, Francium. You can remember them as those that form the Alkali bases, Sodium Hydroxide (NaOH), and Potassium Hydroxide (KOH) among others. In Pure Metallic form, they would have a neutral charge. However, they are frequently found in ionic form where they loose an electron to form a positive ion with a +1 charge. Li+ Na+ K+ etc.
A higher cation charge concentrated on the smaller cations makes it hard to pull apart ionic lattices
Cations are positive.
alkaline earth metals and alkali metals have 2 and 1 electrons in their outer most shell and are not tightly bound to nucleus so they are ready to lose their outer most electrons to form mono and divalent cations.
The properties of alkali earth metals and alkaline metals want to give up or share their valence electrons when bonding with a non-metal or polyatomic ion. For example, Sodium (Na) has a single valence electron, and if it bonds with Chlorine (Cl) which has seven valence electrons, Sodium would give up and share it's electron with Chlorine. Because an electron is negatively charged, and a proton, inside the nucleus, is positively charged, the Sodium atom has one less negative charge, and one more positive charge, rendering the ionic charge no longer neutral but +1. This is why metals are able to form cations.
