How many electrons would you expect chlorine with an atomic number of 17 to have in its outer shell?
Chlorine has 17 electrons, distributed in the following way: 2 in first shell 8 in second shell 7 in third (outer) shell Therefore Chlorine has 7 electrons in its outer shell.
The electron configuration for an element in the halogen group should always end with what?
The simply answer is that in the outer shell each of the halogens have only seven electrons, this is the reason why they are the most reactive nonmetals, they wish to require a further electron to become stable. Fluorine (F) Atomic number 9 [He] 2s22p5 note the second shell is the outer shell and has only 7 electrons, to be stable it has to have eight. Chlorine (Cl) Atomic number 17 [Ne] 3s23p5 note this its the third shell which is the outer shell and has only 7 electrons, to be stable it has to have eight. For Bromine (Br) we find its the fourth shell is the outer shell which has seven elections, and finally Iodine (I) we find its the fifth shell which is the outer shell and it has only 7 electrons, to be stable it has to have eight. Hope this helps
What do you call a hard outer skeletal shell?

How can you represent atoms?
First you start of by finding out what the atomic number is of the element, in this case the number is 17. You then draw a circle, you are aloud to put 2 electrons on this circle. you then draw another cirlce around it, you are aloud to have 8 electrons on the outer shells. you will ned a third circle to put the rest of the elcetrons on to it. in total you should have the smallest circle with 2 electrons, the middle circle with 8 and then the outer shell with 7 elecrons on it. you can draw the electrons as dots or crosses on the cirlce line. because the outer shell is not full and only has 7 electrons instead of 8, this means it will be reactive. if an element has a full outer shell then it becomes unreactive. hope that helped. :)
How does the tough outer shell of a coconut protect the seed as it travels?
The tought outer outer shell protects the seed by not making i t able to crack. haha. CRACK! BUTT CRACK! ..thats FUNNY! :DD ! ~T.A.C South Carolina! 2-3-11
What are the Every element in group one has one electron in its outer shell Every element in group two has two electrons in its outer shell?
Both statements are true:Every element in group I has one electron in its outer shell andEvery element in group II has two electrons in its outer shell
Element bromine electrons outer shell?
Bromine has 7 electrons in its outer shell.
How many are in the outer shell of the yellow group?
There are different electrons in the outer shell of each element.
When an electron moves from the outer shell of one element to the outer shell of another element what kind of bond has been created?
This is an ionic bond.
How many electrons are in the outer shell of the yellow group?
There are different electrons in the outer shell of each element.
If an element is chemically active what is the state of its outer electron shell?
The key to "happiness" for an atom is a full outer electron shell. (The outer electron shell is called the valence shell.) There are two conditions that cause a shell not to be full. Either it has only an electron or two (or three) in the outer electron shell or it's short an electron or two in that outer shell. The direct answer to the question is that if an element is chemically active, its outer electron shell is incomplete or is not full.
How many electrons are in the outer shell of copper?
The outer shell (N=4) of the copper element has 2 electrons.
When an atom forms an ion describe the outer shell of the ion?
Depending on the element the furthest shell out, when the outer shell has been filled by an other element donating one electron it turns into an ion.
Which shell determines the chemical property of an element?
the outer shell - which 'wants' to be full.
An element is inactive if?
It has a full outer shell of electrons.
How many electrons does the element B have in its outer shell?
Boron has 3 electrons in the outer shell and 2 electrons in the inner.
What makes an element stable?
an element is stable when it has a full outer shell of electrons. to abide by the octet rule it must have a shell of 2 then 8 electrons. An element with a full outer shell (8) will be stable and act like its nearest noble gas.
