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 does the group number of A elements in the AB numbering system tell about valence electrons?
all the elements in group A has the same number of valence electrons
Elements that have the same number of valence electrons are?
All elements in the same group have the same number of valence electrons.
What is the number of valence electrons for the elements in group 1?
The elements in Group 1 have one valence electron in their outermost s orbital.
How do you use te periodic table to identify the number of electrons available for bonding?
Valence electrons describe the number of available electrons for bonding. The group number describes outermost electron. The elements in same group has same valence electrons.The number of electrons available for bonding are the valence electrons. In an element, the group number is equal to the number of valence electrons. So the number of electrons available for bonding can be identified by the group number.
How many valence electrons can an atom have?
That depends on the element in question. Atoms can have anywhere from 1 to 8 valence electrons. For the main group elements, Groups 1,2,13-18, the number of valence electrons are the number in the one's place in their group number, as follows: Group 1 Elements: 1 valence electron Group 2 Elements: 2 valence electrons Group 13 Elements: 3 valence electrons Group 14 Elements: 4 valence electrons Group 15 Elements: 5 valence electrons Group 16 Elements: 6 valence electrons Group 17 Elements: 7 valence electrons Group 18 Elements: 8 valence electrons The transition metals, Groups 3 - 12, are more complicated because they are adding d electrons, some of which behave like valence electrons, and many transition metals can have different numbers of valence electrons. For example manganese can have anywhere from 2 to 7 valence electrons.
What is the different about the valence electrons for all elements in a group?
The valence electrons for elements in the same group stay the same, since the number of valence electrons corresponds to the group number.
Where are elements with the same number of valence electrons?
All elements in the same group have the same number of valence electrons.
Where do elements have the same number in valence electrons?
Elements in the same group have the same number of valence electrons.
What does the group of A elements tell about valence electrons?
All elements in the same A group will have the same number of valence electrons.
What does the group number of A elements in the AB numbering system tell about valence electrons?
all the elements in group A has the same number of valence electrons
The elements within a group have a similar number of?
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
What does the group number of a element tell about valence electrons?
All elements in the same A group will have the same number of valence electrons.
What are the elements that have the same number of valence electrons?
The elements that have the same number of valence electrons are located in a group.The group number from the Periodic Table relates to the number of electrons in the valence shell.For example, elements in group 1 (H, Na, Li, K, Rb, Cs, Fr) all have 1 valence electrons and elements in group 7 (Cl, F, I, Br) have 7 valence electrons in its outer shell.
What have the same number of valence electrons?
All elements in the same group have the same number of valence electrons.
Elements that have the same number of valence electrons are?
All elements in the same group have the same number of valence electrons.
What does the group number A elements (in the AB numbering system) tell about valence electrons?
The group number tells you the number of valence electrons present.
What does the group number of A elements (in the AB numbering system) tell about valence electrons?
The group number tells you the number of valence electrons present.
