A chloride anion contains eight outer shell electrons, one more than the seven outer shell electrons found in a chlorine atom.
Chlorine is a chemical metal element. There are 17 electrons in a single atom.
Seven electrons on the outer shell of chlorine.
8
7 electrons
a covalent bond means sharing of electrons the outer most electrons on chlorine shell is 7since chlorine is a diatomic molecule (cl2) it comprises of 2 chlorine atoms having 7in each valence shell. for this molecule to be stable it must attain the stable octet configuration 8electrons in their outer shell x x x Cl x x x x 1 o o o o Cl o o o so they share the electrons (marked with a hyphen) to attain the stable configuration. this sharing of electrons between two chlorine molecules is called sharing of electrons within chlorine
5 electrons in p orbitals in the outer shell. Cl has an electronic configuration of [Ne] 3s2, 3p5 In level 2 there a further 6 electrons in p orbitals making 11 electrons in total occupying p orbitals
it has 7 electrons in its outer shell, which means its charge is -1.
The electronic configuration for Cl atom is 1s2 2s2 2p6 3s2 3p5. It has one unpaired electron in the 3p shell, thus it is a free radical and very reactive. Hence chlorine does not exist in its atomic state as a Cl atom as it is too unstable.
.. H : Cl : .. put a full valence shell around chlorine (Cl) and put Hydrogen (H) to the left next to a pair of electrons.
Chlorine is a chemical element with the symbol Cl and an atomic number of 17. It has 7 electrons in its outer shell.
The Cl atom gains an electron from another atom, and electrons carry a 1- charge. The Cl atom does this because it has 7 outer shell electrons, which isn't very stable, while an outer shell of 8 electrons is stable.
Eight electrons in the 2nd shell of Br- This is also the number of electrons in the 2nd shell of I-, Cl- and even F- !
a pair of shared electons means that two atoms are covalently bonded together and share electons to fulfill their outer shell. for example, Cl2 consist of two Cl atoms bonded together. If you look on the periodic table you will see Cl is one column away from being a noble gas and having a full outer shell. this means that in Cl's outer shell there are 7 electrons. all atoms want 8 electrons. thus two Cl atoms will bond together and share there lone electon in order to both have an octet ( 8 electons in outer shell and become neutral and stable. electons always come in pairs if there is an odd number of valence electrons (7 in Cl and others in the same column)) this means the atom has one electorn by itself and will bond with another atom in the same situation to share and fill outer shell.
The outer shell on phosphorus (P) has 5 electrons -- it needs 3 electrons The outer shell on chlorine (Cl) has 7 electrons -- it needs 1 electron The electronegativity of P is about 2.2 The electronegativity of Cl is about 3.2 -- it will attract electrons slightly more So the simplest arrangement here is: PCl3 (P shares three electrons, and each Cl shares one.) They are just sharing electrons (covalent bond). If the electronegativities were a little stronger (delta of 1.7 is the magic number), then you could have an ionic bond -- but in this case both atoms need electrons, so ionic bonding wouldn't occur with P and Cl.
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
Cl-Cr-Cl
When a chlorine atom, which normally has 7 electrons in the valence shell, gains an electron, it achieves a stable state similar to the noble gas, having 8 electrons in the outer shell. This results in the formation of the chloride ion, Cl-.
The elements that have the same number of valence electrons are located in a group.The group number from the Periodic Table relates to the number of electrons in the valence shell.For example, elements in group 1 (H, Na, Li, K, Rb, Cs, Fr) all have 1 valence electrons and elements in group 7 (Cl, F, I, Br) have 7 valence electrons in its outer shell.
The chloride ion has a negative charge; Cl-. You can tell because chlorine is on the right side of the periodic table in the second column from the right. All elements in this column have a charge of -1.
The halogen family, F,Cl,Br,I,As all have outer shells with 7 electrons
Let's look at salt NaCl Na is extremely dangerous, it will react with water and produce H2 gas and enough heat to burn the gas. Cl is a poisonous gas. Na has 1 electron in the 3s orbital. It wants 2 electrons in the 3s orbital to be very stable. Cl has 7 electrons in the 3rd shell, 2 in the 3s and 5 in the 3p orbital. It wants 1 more electron to have 8 electrons in the 3rd shell and be very stable. Cl takes 1 electron off the Na atom and they are both stable. It all depends on the number of electrons in the outer shell.
