Does group 2A elements lose or gain protons or electrons?
Group 2A elements tend to GAIN electrons!!
When elements gain three electrons to fill its valence energy level?
When these elements have five electrons on the outermost shell of electrons.
Does group 13 elements lose or gain valence electrons?
It is going to lose electrons
Do elements in group 7 gain electrons when they react?
Yes I think so
What do atoms of group 17 elments give off when they gain electrons?
No it does not.
Does group 2A elements lose or gain protons or electrons?
Group 2A elements tend to GAIN electrons!!
When elements gain three electrons to fill its valence energy level?
When these elements have five electrons on the outermost shell of electrons.
Does group 13 elements lose or gain valence electrons?
It is going to lose electrons
Why do elements in group 18 rarely react with other elements?
Elements in Group 18 already have an octet of electrons, which is a full outer shell of 8 electrons. An octet of electrons makes the element stable, so it does not need to react with any other elements to gain or lose electrons.
Which compounds are tetravalent?
Tetravalent means having 4 valence electrons. The elements in the 14th group are tetravalent. They do not lose or gain electrons. they gain electrons.
What does it it mean to say that some elements are reactive and form ions easily whereas others do not?
Elements form ions by either gaining or losing valence electrons. The elements that lose electron(s) and gain electron(s) acquire a positive charge and negative charge respectively. The elements that lose and gain the least electrons require less ionization energy, and are more reactive than elements that need to lose or gain more electrons. For instance, elements in group 1 of the Periodic Table need to lose one electron, and are more reactive than elements in group 2 that need to lose 2 electrons.
What tends to gain electrons?
Elements on the right of the periodic table but not in group 0/8 tend to gain electrons. Those in group 7 tend to gain 1 electron and those in group 6 tend to gain 2.
Do elements in group 7 gain electrons when they react?
Yes I think so
Elements in Group 16 of the periodic table usually?
Oxygen, Sulfur, Selenium, Tellurium, and Polonium =]

How many electrons does group 7A need to become stable?
In the modern periodic table, these elements belong to group 17. These elements have s2 p5 electron configuration. Hence they need one more electron from an electron donor to fulfill its valence shell to obtain noble gas configuration.The elements in the group 7A has 7 electrons in their outermost energy level. They gain 1 electron to get the noble gas configuration. The elements in the group 7A are called halogens.
What group of elements gain two valence electrons when the atom form ionic bond?
Group 16 or the chalcogens.
