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

Why are group 8A elements not represented by ionic radius?

they will become another element if they loose or gain 8 electrons


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.


When metals react with other elements the atoms of the metals loose or gain electrons?

They will loose electrons.


What are formed when elements gain or loose electrons?

ions


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!


What type of elements gain and loose electrons as they form bonds?

Metals lose electrons, nonmetals gain electrons.


When you go down the element generally become more or less metallic?

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


If metals loose electrons to non metals are metals now anions?

No, it is not true. When metals loose electrons they become cations.


When atoms become ions their outer most shells of electrons become?

they add or loose electrons from the outer most shells
