The mass of Cl-37 is greater than that of Cl-35. Because Cl-37 has two neutrons more than Cl-35.
Not a neutral Cl atom but the chloride ion Cl- is isoelectronic with the noble gas argon.
One atom of Na and one of Cl
Chlorous acid has 1 H atom, 1 Cl atom and 2 oxygen atoms.
Cl-1 has 17 protons and 18 electrons
Li atom donates one electron to a Cl atom when Li+Cl- is to be formed as ionic compound (salt):Li --> e- + Li+Cl + e- --> Cl--------------- +Li + Cl --> LiCl (or Li+Cl-)
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.
In cl-cl bond 1 electron is sahred by each of Cl atom.
Cl- Chloride ion 1s22s22p63s23p6 Cl Chlorine atom 1s22s22p63s23p5
Then this atom will become an anion (negatively charged) Example: Cl + e- --> Cl-
Cl2: Chlorine atom is Cl and you want two. Two atoms are single, covalently bonded to each other by one shared pair of electrons (one from each atom): (drawn as hyphen - or two dots .. between the 2 atoms)Cl-Cl or Cl..Cl
Cl
Cl.
The anion is chlorine (Cl-).
The mass of Cl-37 is greater than that of Cl-35. Because Cl-37 has two neutrons more than Cl-35.
1 mole Cl = 35.453g Cl 28.4g Cl x 1mol Cl/35.453g Cl = 0.801 mole Cl
Cl H | | N - N | | Cl H Fill in 3 unshared electron pairs around each Cl atom, and one unshared electron pair on each N atom. This molecule has one isomer, shown with the same formation swapping the places of one H atom with one Cl atom. Cl Cl | | N - N | | H H
