Lose 2
Alkaline-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.
What else can I help you with?
When you go down the element generally become more or less metallic?
As you go down a group on the periodic table, elements generally become more metallic. This trend is due to the increase in the number of electron shells and distance between the nucleus and the outermost electrons, which makes it easier for elements to lose electrons and exhibit metallic properties.
What type of elements gain and loose electrons as they form bonds?
Metals lose electrons, nonmetals gain electrons.
If metals loose electrons to non metals are metals now anions?
No, it is not true. When metals loose electrons they become cations.
What charge do elements that loose electrons have?
Elements that lose electrons in reactions have a positive ionic charge. There are exceptions to this, but I'll not over-complicate this!
Why does an element gain or lose electrons to become an ion?
When elements react with other elements, they gain or loose electrons. Electrons are the reason that some elements react and others do not. Each element wants to have eight outer electrons. This is called the octet rule. (oct means eight). However, most elements do not have eight (except for the elements in the 18th column of the periodic table). The periodic table shows how many electrons each element has on its outer-layer. The last number of the column # (in the periodic table) is the number of electrons that the element contains in its outer-ring. For example, elements in the first column have one. Another way is when substances burn and reach oxygen. This is called oxidation reaction.
When metals react with other elements the atoms of the metals loose or gain electrons?
They will loose electrons.
Why are group 8A elements not represented by ionic radius?
Group 8A elements, also known as the noble gases, do not form ions because they have a stable electron configuration with a full outer shell of electrons. This means they do not gain or lose electrons to achieve a stable configuration, so the concept of ionic radius is not applicable to them.
What happens when ionization energy change when moving down a group of elements?
the ionization energy is increased because of electronegativity when we move down the group the electronegativity is decrees who hold all electrons hardly to gather that's why the electrons loose easily and become an ion.
What are formed when elements gain or loose electrons?
ions

When atoms become ions their outer most shells of electrons become?
they add or loose electrons from the outer most shells
Do metals usually gain or loose electrons to be stable?
Metals will LOSE electrons to become stable.

Describe relationships between elements using the periodic table.HELP?
As you go across the periodic table from left the right the metallic nature decreases and the non- metallic nature increase. As we go down the group of atoms on the metal side the atoms get bigger and being metals loose electrons more easily therefore become more reactive As we go the group of atoms on the non metal side the atoms get smaller and are less likely for electrons to be gained
