For Group 2A metals, the electron in the outermost shell (valence electron) is the most difficult to remove because it is closest to the nucleus and therefore experiences a stronger attraction to the positively charged nucleus. This makes it harder to remove compared to inner shell electrons.
For group 2A metals, the electrons that are the most difficult to remove are the third ones. This is because the largest ionization energy happens between it and the second electron.
Lithium has the highest ionization energy because ionization energy increases to the right and decreases downward on a periodic table.

Which group has 1 valence electron?
Group 1 elements, also known as alkali metals, have 1 valence electron. Examples include lithium, sodium, and potassium.
What group loses 1 electron to form ions?
Group 1 elements (alkali metals such as sodium, potassium) lose 1 electron to form ions with a +1 charge.
What is the difference between alkali metal and group 2 metals?
Alkali metals belong to Group 1 of the periodic table and include elements like lithium, sodium, and potassium. Group 2 metals are known as alkaline earth metals and include elements like magnesium and calcium. The main difference is that alkali metals are more reactive than Group 2 metals because they have one valence electron, while Group 2 metals have two valence electrons.
What family or group is desperate to get rid of an electron?
The group that is desperate to get rid of an electron is the alkali metals. These elements have one electron in their outermost shell, and they readily lose this electron to achieve a stable electron configuration.
If an element has 1 valence electron what group is it in?
If an element has 1 valence electron, it is in Group 1 of the periodic table, also known as the alkali metals. Examples of elements in this group include lithium, sodium, and potassium.
Which group in the periodic table loss electron?
Alkali metals, Ist group.
Which group of metals is characterized by a single valence electron and reactive atoms?
Alkali metals
Which group has 1 valence electron?
Group 1 elements, also known as alkali metals, have 1 valence electron. Examples include lithium, sodium, and potassium.
What group of elements react by losing one electron?
The alkali metals in group 1 react by losing one electron.
The group that has one electron in its outer level?
This group is known as the alkali metals, and they consist of elements in Group 1 of the periodic table such as sodium and potassium. Having one electron in their outer level makes them highly reactive and eager to lose that electron to achieve a stable electron configuration.
Which group metals are very reactive with one electron in the outer energy level?
Alkali metals
Why are the metals in the first group of the period table so reactive?
These metals lose easily an electron.
What group loses 1 electron to form ions?
Group 1 elements (alkali metals such as sodium, potassium) lose 1 electron to form ions with a +1 charge.
Which elements are likely to lose electron?
Group I elements (that is alkali metals)
What is the difference between alkali metal and group 2 metals?
Alkali metals belong to Group 1 of the periodic table and include elements like lithium, sodium, and potassium. Group 2 metals are known as alkaline earth metals and include elements like magnesium and calcium. The main difference is that alkali metals are more reactive than Group 2 metals because they have one valence electron, while Group 2 metals have two valence electrons.
Why is hydrogen placed in group one of the periodic table?
Hydrogen is placed in group 1 of the periodic table because it has one electron in its outer shell, making it chemically similar to the alkali metals in that group. However, hydrogen is unique because it can exhibit characteristics of both group 1 metals and nonmetals depending on the chemical environment.
What family or group is desperate to get rid of an electron?
The group that is desperate to get rid of an electron is the alkali metals. These elements have one electron in their outermost shell, and they readily lose this electron to achieve a stable electron configuration.
