Cl-
Chlorine is a non metal and it reacts by gaining electrons rather than losing inorder to attain a stable electron configuration of the noble gases.
They achieve stable configuration by sharing their electrons in their outermost shell.
A chlorine atom needs one additional electron in order to become stable.
Oxygen atoms need to share or gain two electrons in order to achieve a stable electron configuration.
The electron configuration of copper is: [Ar]4s13d10. It isn't 4s23d9 because Cu is able to obtain a more stable electron configuration when it takes an electron from the 4s and adds it to 3d. A half filled 4s and a completely filled 3d is more stable.
Cl-1.
Cl - This means that Chlorine has an extra electron, so it's negative. Chlorine already has 7 electrons and in order to be stable, it only needs one more electron.
What symbol would represent a chlorine ion that has ionized to have a stable electron configuration?
two chlorine atoms
No. Chlorine's electron configuration is unstable. As a result, chlorine is a highly reactive element.
The atomic number of Sodium is 11 (2,8,1), so there is one electron in the outer-most shell. As soon as sodium looses this outer-most one electron, it acquires the stable most structure with a 2,8. That';s why sodium ion is stabler than sodium metal. The electronic configuration of a sodium ion is 2,8. Same thing happens with Chlorine. The electronic configuration of chlorine is 2,8,7. Chlorine needs just one electron to stabilize itself with a configuration of 2,8,8. When the chlorine atom gains one electron, it forms the chlorine ion which has the configuration 2,8,8 which is stable.
Chlorine is an element from group 17. It needs one electron from another atom to obtain the stable electron configuration. In ionic compounds it becomes the chloride ion with -1 charge.
Sodium has 1 electron to "donate" and chlorine has space to "accept" 1 electron, so this electron transfer occurs and both have a stable octet electron configuration
Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration. Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration.
Chlorine is a non metal and it reacts by gaining electrons rather than losing inorder to attain a stable electron configuration of the noble gases.
Generally, atoms would want to fulfill the octet rule: 8 electrons in the valence shell. This gives the atom a noble gas configuration and is seen as stable. Since the Chlorine atom is in group 7 of the periodic table, it "prefers" to gain one electron instead of losing 7 to attain the stable octet configuration.
Chlorine atom has 17 electrons. It is readily accepting an electron from another atom to obtain its stable electron configuration (of argon). A chloride ion has 18 electrons.
