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.
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.
How is helium similar to group two elements?
helium has 2 valence has electrons. Group 2 elements also have 2 valence electrons.
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 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.
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.
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.
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.
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
How is helium similar to group two elements?
helium has 2 valence has electrons. Group 2 elements also have 2 valence electrons.
How many valence electrons does group 8 have?
Elements in group 8 all have 8 valence electrons, this is why these elements are in group 8, they are called noble gases, some examples are Argon, Xenon,
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.
