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).
Which group of elements wants to give away 2 electrons?
group 2
How many electrons will the elements have in the second group have on the periodic table?
There are 2 valence electrons (electrons in the outer shell) of group 2 elements in the ground (un-ionised or standard) state. This causes them to form +2 ions.
Which group on the periodic table loses 2 electrons to create an ion?
The elements in group 2 lose 2 electrons to create an ion.
Why do group 2 elements tend to lose 2 electrons in a chemical reaction?
Group 2 elements are all metals, which already tend to lose 2 electrons. A simple way of explaining why group 2 loses two electrons is that atom's are most stable with 8 valence electrons, group 2 has has 2 valence electrons and therefore it is easier to lose 2 rather than gain 6.
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 is helium similar to group two elements?
helium has 2 valence has electrons. Group 2 elements also have 2 valence electrons.
Which group of elements wants to give away 2 electrons?
group 2
The number of valence electrons in group 2 elements is?
2
How many electrons will the elements have in the second group have on the periodic table?
There are 2 valence electrons (electrons in the outer shell) of group 2 elements in the ground (un-ionised or standard) state. This causes them to form +2 ions.
Which group on the periodic table loses 2 electrons to create an ion?
The elements in group 2 lose 2 electrons to create an ion.
How many veilance electrons does radium have?
Radium is a group 2 element. All group 2 elements have 2 valence electrons. Thus, radium has 2 valence electrons.
What is the relationship between valence electrons and there location on the periodic table?
The first group elements have 1 dot on their electron dot diagram, the group 2 elements have 2, group 3-12 elements have 2 electrons (with exceptions), group 13: 3 electrons, group 14: 4 electrons, group 15: 5 electrons, group 16: 6 electrons, group 17: 7 electrons, and group 18: 8 electrons.
What sublevel in group 2 elements are valence electrons?
s
Why do group 2 elements tend to lose 2 electrons in a chemical reaction?

What are the valence electron of an atom?
The valence electrons are found on the valence shell, the outermost shell of an atom. By using the periodic table and the group numbers, one can find the number of valence electrons for elements in groups (vertical columns) 1-2 and 13-18. For the 1st 2 groups (1 and 2), the group number tells the number of valence electrons for elements which belong in that group Elements in the 1st group have 1 valence electron and elements in the 2nd group have 2 valence electrons. For groups 13-18, refer to the tens' value (the teen value that is not the "1" in these cases). Elements in group 13 have 3 valence electrons, elements in group 14 have 4 and so on to the the final group, 18, where electrons have a full octet of valence electrons.
Why do elements in group 2 have the same properties?
All these elements have two valence electrons.
