Alkaline Earths will most easily lose an electron. This is because the have a smaller alkali radii than alkali metals causing them to not be as tightly bound to the nucleus. This makes the more readily lose their electrons.
The Alkali Metals, which are the elements in Group 1 of the periodic table, each have one lone electron in their valence shell. And each of these elements wants to get rid of that single electron. These metals, which include lithium, sodium, potassium, rubidium, caesium and francium, are the most likely to lose electrons.
The electron affinity of an element can be either positive or negative, depending on whether the element tends to gain or lose electrons when forming chemical bonds.
Barium would lose an electron more readily, because its outer electrons are farther away from the nucleus than those in magnesium, and thus are not held as tightly. =] Hopefully this helps you out alot.
The electron arrangement of metallic elements typically involves one or two electrons in the outermost shell, which allows them to easily lose electrons and form positive ions. This electron arrangement gives metallic elements their characteristic ability to conduct electricity and heat well.
The valence electron of a lithium atom is in the 2s orbital. It is easily removed to form a lithium ion with a charge of +1 because lithium only has one valence electron, making it relatively easy to lose.

Na, sodium, should have the lowest first ionization energy of those four elements.
Valence electron describes type of element. It either lose or gain electron.
The property of the element sodium is that it is a highly reactive metal that is soft and silvery-white in color. Sodium is known for its tendency to easily lose an electron, making it a key component in many chemical reactions.
The electron affinity of an element can be either positive or negative, depending on whether the element tends to gain or lose electrons when forming chemical bonds.
As we go down the group, nuclear charge deceases and atomic radii increases. So the element can easily lose electron and hence react.
Barium would lose an electron more readily, because its outer electrons are farther away from the nucleus than those in magnesium, and thus are not held as tightly. =] Hopefully this helps you out alot.
Metals are the elements that usually lose electrons in their chemical reactions. This is because they have few electrons in their outermost shells which are easily lost.
The electron arrangement of metallic elements typically involves one or two electrons in the outermost shell, which allows them to easily lose electrons and form positive ions. This electron arrangement gives metallic elements their characteristic ability to conduct electricity and heat well.
The elements in the halogen family are in group 7 and thus have 7 valence electrons. They are very reactive because the want an additional electron to complete the octet. They can get this additional electron by reacting with another element willing to donate that electron. A perfect example is an element from group 1 or 2 (alkali or alkali earth) which wants to donate an electron.
Sodium is indeed a period 3 element in the periodic table. It is classified as an alkali metal and is highly reactive due to its tendency to lose its outermost electron easily.
Francium has the lowest electronegativity and fluorine the highest.
