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.
Elements in Groups 1A, 2A and 3A do not gain electrons when they form ions. Instead, they are giving away electrons which makes them become cations, a positively charged ion. The nonmentals tend to be anions, because they gain the electron, making it into a negative ion.
No, metals form cations, which means that they lose electrons and become positive
Metals lose electrons to form positive cations
Metals in groups 1-3 form ions by losing electrons, thus becoming cations.
Group 2 contain alkaline earth metals: the elements loose electrons and become cations.
They lose electrons and become positive.
Elements that lose electrons in reactions have a positive ionic charge. There are exceptions to this, but I'll not over-complicate this!
Metals lose electrons, nonmetals gain electrons.
as you go down a group the elements become more metallic. why? ionization energy decreases. ionization energy is the amount of energy needed to remove the most loosely held electrons. when electrons are lost, a metal is formed. so as you go down a group, the electrons are futher away from the nuclear pull (because the period increases). therefore, not much energy is needed to remove the electrons making it easier to loose them
No, it is not true. When metals loose electrons they become cations.
they loose electrons from its outershell
they will become another element if they loose or gain 8 electrons
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.
They will loose electrons.

they add or loose electrons from the outer most shells
Metals will LOSE electrons to become stable.

Calcium can loose 2 electrons. Oxygen can gain 2 electrons.
