Elements tend to lose electrons and become positively charged ions if they have a few electrons more than a filled energy level. Elements like Lithium, Sodium, Potassium all have a tendency to lose one electron when bonding with other atoms.


It is a matter of bonding most effectively.


Beryllium, Magnesium, Calcium tend to lose 2 electrons when bonding.

Elements in Group 1 become more stable by what an electron?

Elements in group two become more stable as they all have complete electron shell.They do not have valence electrons and hence they are less reactive.Some of the elements of group 2 are Barium,Magnesium and Calcium


Which of these can become stable by losing 1 electron calcium argon sodium nitrogen oxygen chlorine?

Sodium can become stable by losing 1 electron, forming a sodium ion with a 1+ charge, with the formula Na+. By losing its single valence electron, the resulting sodium ion achieves the noble gas configuration of neon, so that it has an octet (8) of valence electrons.


What makes some elements ions?

Some elements become ions by gaining or losing electrons to achieve a stable electron configuration. When an element gains electrons, it becomes a negative ion (anion), while losing electrons results in a positive ion (cation). This process allows the element to achieve a full outer electron shell and become more stable.


Why does lithium bond?

Lithium bonds due to its tendency to lose an electron and achieve a stable electron configuration. By losing this electron, lithium can attain a full outer energy level, making it more stable and forming bonds with other elements to satisfy its electron needs.


How does a unstable atom with one valence electron become stable?

Generally by losing the one electron


Is sodium stable by losing 1 electron?

No, sodium is stable by losing 1 electron in order to achieve a full outer electron shell and become a positively charged ion called Na+.


What type of elements become cations?

Metals typically become cations by losing electrons to attain a stable electron configuration. Transition metals and main group metals are common examples of elements that form cations.


Is sodium's outer shell stable?

No, sodium's outer shell is not stable because it only has one electron in its outer shell. Sodium will readily react with other elements to achieve a stable electron configuration by losing this electron.


Can calcium become stable by losing 1 electron?

Calcium loses its two valence electrons to become Ca 2+ ion.


How many electrons does potassium need to gain or lose to become stable?

Potassium (K) needs to lose one electron to become stable, as it belongs to group 1 in the periodic table and has one electron in its outer shell. By losing this electron, potassium achieves a full outer shell and attains a stable electron configuration.


What elements have the highest IE?

Helium has the highest ionization energy (IE) among all the elements, as it has a fully stable electron configuration that resists losing an electron. Other elements with high ionization energies include neon, followed by elements in the noble gas group due to their stable electronic configuration.


Some elements can become stable either by gaining or losing electrons. They are called?

They are called ions
