How many electrons are in the outermost energy level of a chloride ion (Cl-) in table salt?
There are 8 electrons in the outermost energy level of a chloride ion (Cl-) in table salt. This is because chlorine has 7 electrons in its neutral state, and when it gains an electron to become Cl-, it has a full outer shell with 8 electrons.
Chlorine (Cl) can be found as an ion with a 1- charge. How does this happen?
Chlorine (Cl) can gain an electron to achieve a full outer shell of electrons, forming the chloride ion (Cl-). This results in a negatively charged ion, as it now has one more electron than protons.
What is the Covalent Bond for Chlorine and Chlorine?
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
How does the octet rule explain the formation of a chloride ion?
The chlorine atom is in group 17 of the periodic table of elements, so it has 10 inner electrons and 7 outer "valence" electrons. In forming the chloride ion, it becomes negatively charged by gaining an additional electron in the outer shell, so the valence electron shell now has 8 electrons, as per the octet rule.
What 2 ion is isoelectronic with cl?
The ions that are isoelectronic with Cl- are Ar and K+. These ions have the same number of electrons as Cl- (18 electrons) but a different number of protons.
How many electrons does chlorine have in it's outer shell?
Chlorine has 7 electrons in its outer shell. It needs one more electron to achieve a full outer shell of 8 electrons, which is why chlorine typically gains an electron to form Cl- ion in chemical reactions.
How is cl- ion formed by the cl atom?
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.
How many electrons are in the second shell of ion Br -1?
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- !
Does chlorine have 6 electrons?
Chlorine typically has 17 electrons. In its ground state, chlorine has 7 valence electrons in its outer shell. When it gains one electron, it becomes Cl-, making its total number of electrons 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

Two pair of shared electron are?
In a covalent bond, two pairs of electrons are shared between two atoms. This sharing of electrons helps both atoms achieve a more stable electron configuration by filling their outer electron shells. The shared electrons create a bond that holds the atoms together in a molecule.
Does Cl have a negative or positive charge?
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.
What are the elements that have the same number of valence electrons?
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.
What happens when a chlorine atom gains electron in its outer energy shell?
When a chlorine atom gains an electron in its outer energy shell, it becomes a negatively charged ion known as chloride ion (Cl-). This ion has a full outer energy level and is more stable than the neutral chlorine atom.
How many total electrons and valence electrons are found in an atom of Cl?
In an atom of Cl, there are 7 valence electrons. If you look at a Chemistry Reference table (2002 edition) pages 8 and 9, (visit the link below), you can see that underneath Cl there are the numbers 2-8-7. The last number is the number of valence electrons. This is found for any element on the Period table.
