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.
What is the first element that needs the third shell?
Sodium, assuming "first" means "first in the periodic table", i.e. the one with fewest electrons per atom. The first shell holds 2 electrons, and the second holds another 8. So the element with atomic number 11 is the first one to need the third shell, and that's sodium.
What is the number of energy shells in a carbon atom and how many electrons are in each shell?
In a Carbon atom there are two electron shells. The first shell can only hold two electrons therefore it is full ( 2 electrons in the first shell) and in the next shell there are 4 electrons. Remember: 2 e- in the first shell only up to 8 e- in the second and third shells. ("e-" usually short form for "electronsnegative charge") and some other thing to keep in mind are: Atomic # = the number of protons and the total number of electrons Atomic mass # = protons + neutrons (labled proton = p+ and neutron n0) So, Carbon is #6 on the Periodic Table of Elements therefore has 6 protons in its nucleus and 6 total electrons around it. Hope this was useful!!!! ;)
Which elements has 3 electrons in its outermost shell?
Elements having electrons in their third valence shell can be found in the third row of the periodic table (elements 11-18).
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 element has 2 electrons in the first shell 8 second shell and 6 in the third shell?
This element is sulfur (S), with 2 electrons in the first shell, 8 electrons in the second shell, and 6 electrons in the third shell.
How many electrons can the second shell of an atom hold?
First Shell always has 2 electrons. Second shell onwards can have up to a maximum of 8 electrons.
How many electrons are in the first shell second shell and third shell of neon?
It depends what electronic state it's found in, but in it's ground state (natural form) it has two electrons in the first shell, eight in the second and none in the third. This is because it has an atomic number of 10. 2+8 = 10.
How many electrons does sulfur have in its third electron shell?
Sulfur has six electrons in its third electron shell.
You have 2 electrons in the first shell 8 in the second shell and 6 in he third shell?
Sulfur
I have two electrons in the first shell 8 in the second and 6 in the third shell?
It is sulphur.
What element is 2 electrons in the first shell and 8 in the second shell and 6 in the third shell?
sulphur
What eleme has 2 electrons in the first shell and 8 in the second and 6 in the third?
What element has 2 electrons in the first shell and 8 in the second and 6 in the third
2 Electron in firsat shell 8 electrons in second shell and 6 electrons in third shell?
No, its two electrons in the first, 8 electrons in the 2nd and 3rd shell if its stable
Which element has 2 electrons in the first shell 8 in the second and 6 in the third shell?
Silicon.
What element ahs 2 electrons in the first shell 8 in the second shell 6 in the third shell?
Sulfur
How many of protons and electrons in each shell of sulfur?
firstly the protons are in the nucleus of an atom. there are 16 protons there. the number of electrons is the same as the number of protons. the electron arrangement is as follows: first shell-2 electrons second shell - 8 electrons third shell - 6 electrons this can also be written as 2,8,6
