Does group 2A elements lose or gain protons or electrons?
Group 2A elements typically lose electrons to form a +2 cation with a full outer electron shell. They do not gain protons or electrons, as their positive charge is due to the loss of electrons.
Family of elements that gain of share three electrons when they react?
nitrogen
What kind of elements lose 3 electrons when they react?
halogens, obviously! these gain electrons the most easiest since they are "hyperactive" as I would like to say.
Elements react with other elements based on the number of what in their outer shell?
Elements react with other elements based on the number of electrons in their outer shell, also known as valence electrons. Elements are most stable when their outer shell is full, so they will either gain, lose, or share electrons in order to achieve a full outer shell.
When nonmetals and metals react which atom electrons?
Metals loss electrons and nonmetals gain electrons.
What happens to atoms of most nonmetals when they react with other elements?
They tend to gain electrons when reacting with a metal. Metals generally are short of a full octet by 1 to 4 valence electrons. It is easier to drop 2 electrons than try to gain 6 electrons. The elements in group four can go either way, but the other metals will give up electrons, and non-metals will take them.
Elements in Group 16 of the periodic table usually?
Elements in Group 16 of the periodic table usually have six valence electrons and are nonmetals. They tend to form -2 anions when they react with other elements. These elements are known as the chalcogens and include oxygen, sulfur, and selenium.

Group 2A elements typically lose electrons to form a +2 cation with a full outer electron shell. They do not gain protons or electrons, as their positive charge is due to the loss of electrons.

nitrogen
When metals react with other elements the atoms of the metals loose or gain electrons?
They will loose electrons.
What elements gain 2 electrons when they combine with another element?
The elements that gain two electrons when they react are the ones found in group 14 of the periodic table. Oxygen is a good example of such elements.
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.
What does it mean to say that some elements are reactiveand form ions easily whereas others do not?
Basically when elements react they either gain or lose electrons until their outer shell has eight (apart from helium and hydrogen). When elements react and gain or lose electrons they become ions as the number of protons is no longer proportional to that of electrons. elements with a large or low amount of electrons (1 or 7) on their outer shell react easily E.g the alkali metals (group 1 of the periodic table) have only one electron and so must be preserved in oil or they will react with even the air in the atmosphere.
Why don't group 0 elements react?
Group 0 elements, also known as noble gases, have a full outer electron shell which makes them very stable. They do not react because they have no tendency to gain, lose, or share electrons to achieve a stable electron configuration.
What kind of elements lose 3 electrons when they react?
halogens, obviously! these gain electrons the most easiest since they are "hyperactive" as I would like to say.
