When elements of group 2 lose their valance electrons what would be their charge?

The charge would be positive because the electrons and protons are of equal number so they cancel each other. So if you take the electrons from the element it leaves it unbalanced with x number of protons.

∙ 11y agoThe alkaline earth metals lose two electrons and form an ion with a +2 charge.

∙ 10y agothey give them away or share them with group 6 because they need 2 more electrons to have a full outer energy level

What has 5 electrons in its outer shell?
If you are talking about the valance electrons any elements in group 5 on the periodic table will have 5 valance electrons.
How many valence electrons does magnisium oxide have?
MgOMagnesium: 2 Valance Electrons (Charge is +2)Oxide: 6 Valance Electrons (Charge is -2)Hint: Oxide has a charge of -2 and so does Oxygen. Check the periodic table for the elements that have a -2 charge (group 16) and you will find oxygen as the first element in that group. Periods define how many energy levels the element has, just so you know. Oh and this is ionic.Hope this helps!
Valencies of all elements?
The valency of an element refers to the combining power of a given element. The valencies of all the elements is contained in the table of valencies. The valencies of the elements can be obtained by looking at the groups in the periodic table.
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
How many electrons does a nitrogen atom have in the outermost energy?
5, it is the number of valance electrons determined by the roman numeral over the group in the periodic table of elements
What has 5 electrons in its outer shell?
If you are talking about the valance electrons any elements in group 5 on the periodic table will have 5 valance electrons.
How can the number of valence electrons be determined from the periodic table?
By looking at the group number you can tell how many valance electrons there are ex: Group 1= 1 valance electrons Group 2-12= 2 valance electrons Group 13= 3 valance electrons Group 14= 4 valance electrons Group 15= 5 valance electrons Group 16= 6 valance electrons Group 17= 7 valance electrons Group 18= 8 valance electrons
How many valance electrons does halogen have?
Halogens are group 17 elements. They have 7 valence electrons.
How many electrons do group 1 have in there oter shell?
Group I A elements have 1 valance electron.
How many Valance electrons in oxygen?
6 Use the periodic table as a guide. As you go across from left to right the number of valence electrons increases. H = 1 Be = 2 B = 3 C = 4 N = 5 O = 6 F = 7 This trend stays the same all the way down each column. Usually periodic tables are marked on the top with roman numerals or something to signify how many valence electrons each element has.

How many electrons are in oxygen's outer level?
The word "valance" is used to describe electrons in the outer-most energy level of an atom. Oxygen has six valance electrons.
What are the names of the four elements of VII A group?
Group 7 elements are halogens. They have seven valance electrons& are highly reactive. They are: -Fluorine -Chlorine -Bromine -Iodine
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
What elements have the same number of valance electrons as boron?
All in the same group: 13 (or 3) like Al, Ga, In.
