I believe they are the Alkali Metals and the Alkaline Earth Metals
Group 6A, the Oxygen family, takes on two electrons. Elements in this family are: oxygen, sulfur, selenium, tellurium and polonium.
the elements of group-2(eg.- calcium, magnesium etc.) easily loses two electrons to form cations.

Would you expect it to be harder to remove an electron from Na or O?
It would be easier to remove an electron from Na compared to O. Sodium (Na) has a smaller effective nuclear charge and a larger atomic radius compared to oxygen (O), making its valence electron easier to remove. Oxygen has a higher electronegativity and a stronger pull on its electrons, making it harder to remove an electron from O.
Why is the ionization energy needed to remove the first two electrons from Magnesium atoms relatively low?
The ionization energy needed to remove the first two electrons from Magnesium atoms is relatively low because these electrons are in the outermost energy levels and experience less electron-electron repulsion, making them easier to remove compared to inner electrons. Additionally, Magnesium has a relatively small effective nuclear charge, which further reduces the attraction between the nucleus and the outer electrons, making them easier to remove.
Why do non metallic elements pull electrons so effectivley during a reaction?
Non-metallic elements have a high electronegativity, meaning they have a strong attraction for electrons. This allows them to effectively pull electrons towards themselves during a chemical reaction, especially when they are reacting with metallic elements that typically have lower electronegativities. This electron transfer can result in the formation of ionic compounds or covalent bonds, depending on the nature of the elements involved.
What if atoms were unable to gain electrons?
If atoms were unable to gain electrons, elements would not be able to form stable compounds through chemical bonding. This would disrupt many critical processes in chemistry, such as the formation of molecules, reactions between elements, and the stability of substances. It would likely lead to a very different and unstable chemical world.
Do elements in group 2A gain or loose electrons when they become ions?
Lose 2Alkaline-earth metals have 2 outer shell electrons. All atoms "want" eight. They will achieve a full outer shell by losing or gaining the least number of electrons. Since group 2A elements have two valence electrons, they would either have to gain 6 electrons or lose 2. It is easier to lose 2.

Why only 12 elements form ions easier than the rest of the elements in periodic table?
I would imagine that these elements are hydrogen, the alkali metals and the halogens. Hydrogen and the alkali metals only have one outer electron, which is easier to displace than the two outer electrons of the alkaline earth metals, for example. In contrast, the halogens only need one more electron to have a complete outer shell; it is easier to accept one electron than the two electrons needed by the chalcogens - oxygen, sulphur, selenium etc.
Do the elements going horizontally on a periodic table have the same number of electrons?
No two elements would have the same atomic number, so, nor atoms of different elements (in neutral state) would have the same number of electrons.

Where would you find all of the elements with 2 valence electrons?
The elements of the group 2 are some examples.
Can you find out what the element is by the number of electrons in a neutral atom?
Yes, Elements are identified by the amount of electrons it has. Even isotopes are elements are still recognised by their amount of electrons. For example if you had a question: what element has 2 more electrons that Carbon? Carbon has 6 electrons, so 2 more would be 8. That would mean the element would therefore be Oxygen
Does Mercury has two outer electrons?
Yes mercury has two outer electrons the two elements that the two outer electrons would be Iodine and Magnesium.
When elements of group 2 lose their valance electrons what would be their charge?
The charge would be positive because the electrons and protons are of equal number so they cancel each other. So if you take the electrons from the element it leaves it unbalanced with x number of protons.
What are Elements that have less than or more than the normal number of electrons?
These would be ions.
What if atoms were unable to gain electrons?
If atoms were unable to gain electrons, elements would not be able to form stable compounds through chemical bonding. This would disrupt many critical processes in chemistry, such as the formation of molecules, reactions between elements, and the stability of substances. It would likely lead to a very different and unstable chemical world.
The number of electrons in the outermost shell of an element is 5 what is its valency and why?
The valency of the element would be 3, as it can gain 3 electrons to achieve a full outer shell of 8 electrons, following the octet rule. This is because elements tend to gain or lose electrons to achieve a stable electron configuration like the noble gases.
