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 do elements in each group or family have in common?
elements in a group have the same number of valence electrons. The number of shells present increases as we move down a group.
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.
How many valence electrons does boron family have?
The elements in the boron family are in group 13. Therefore, their outermost shells are filled up to their s2 p1 orbitals. That means that the boron family of elements all have 3 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
Why do elements as a family or group share similar properties?
Because they have the same number of valence electrons and need the same number of electrons to fill their valence shells
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 do elements in each group or family have in common?
elements in a group have the same number of valence electrons. The number of shells present increases as we move down a group.
What do elements in a group have in common?
The elements in the same group have the same number of valence electrons and hence similar chemical and physical properties.
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.
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.
Where are elements with the same number of valence electrons?
All elements in the same group have 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.
Why do group one elements have similar properties?
;need the same number of electrons to fill their valece shells ;have the same number of valence electrons
How many valence electrons do elements group 17 have?
There are 7 valence electrons in elements of group-17. They are called halogens.
Where do elements have the same number in valence electrons?
Elements in the same group have the same number of valence electrons.
