In group 2 on the periodic table are they positive ions when they bond with other elements?

Elements from the group 2 of the periodic table form cations.


When do metals become posotively charged?

Metals can become positively charged when they lose electrons to other elements or compounds. This loss of electrons creates an imbalance of positive charges, resulting in a positive charge on the metal.


What is special about the elements in the same group?

elements are in the same group since they react similarly to other elements in that group.


Why is group 18 on Periodic Table of Elements considered inert?

The group 18 elements are considered inert because they rarely if ever interact with other elements. This is due to the fact that their outermost energy levels are full, which means they don't need to bond with other atoms to become stable.


Why is hydrogen separate from the rest of 1A?

Hydrogen is separate from the rest of Group 1A elements because it displays unique properties that do not fit the typical characteristics of alkali metals (Group 1A elements). For example, hydrogen can form both positive and negative ions, while other Group 1A elements typically form only positive ions. Additionally, hydrogen can exhibit nonmetallic properties in addition to metal-like behavior, setting it apart from the rest of Group 1A.


How readily astatine would be to form a salt compared to other elements in Group 17?

Astatine wouldn't form salt as readily as other elements in Group 17. Astatine is a radioactive metalloid. Other elements in Group 17 are nonmetals.


What group off elements do not react with other elements?

Noble Gases


Why lithium and other group 1 elements usually form positive ions while fluorine and other group 17 elements form negative ions?

Because group 1 has 1 electron in it's outer most shell and the have to fill the energy level, so they gave there electron and form positive ion (cation). And group 17 has 7 electrons in it's outer most shell and they need to complete their shell so the gain electron and form negative ion (anion).


Which region of the periodic table is least likely to react with other elements?

Group-18 elements least react with other elements. They are inert in nature. They are called noble gases.Elements in group 18 are less likely to react with any other elements. This group is made out of the noble gases. Its members are He, Ne, Ar, Kr, Xe and Rn.

How do IA and IIA differ the other Group A elements?

base in my experience.... because of the gravity of the earth...


Does potassium reacts positive with all other elements?

Potassium does not react at all with some elements such as helium, but when it reacts, it always forms a positive ion.
