Want this question answered?
Chlorine has: 17 Protons 17 Electrons (in a neutral atom i.e. not an ion) (Isotope Mass Number - 17) is the number of Neutrons.
Cl-1 has 17 protons and 18 electrons
The atomic number of Sodium (Na) is 11.The atomic number of Chlorine (Cl) is 17.There are one Sodium ion (Na+) and one Chloride ion (Cl-) in every Sodium Chloride (NaCl) molecule.
Not a neutral Cl atom but the chloride ion Cl- is isoelectronic with the noble gas argon.
Example: hydrogen chloride (HCl)- the molecule is HCl - two or more atoms binded together; the molecule can be destroyed by chemical procedures.- Cl and H are atoms: an entity made frome the same type of atoms (the same number of protons); it is indestructible by chemical procedures.- an ion (cation or anion) is an atom electrically charged, as H+ or Cl-.
The formula for the chloride ion is 'Cl^-' sometimes written as 'Cl-'
Atoms that have more electrons than protons are called Anions.
the chloride ION is negatively charged (Cl-) And since electron is negative, and protons are positive, it needs more electrons for the ion to be negatively charged.That's how you get the answer! ;)

Cl- Cl-
No, the chloride ion is a single elemental ion, Cl-.
chloride
Chloride ion: Cl-
Protons = 17, electrons = 18There are two isotopes differing in neutron number only :Cl-35 (75%) having 35-17= 18 neutronsCl-37 (25%) having 37-17= 20 neutrons
Cl-1 has 17 protons and 18 electrons
It is NOT an atom but a 1+ ion of Chlorine Cl+ (atomnumber 17, massnumber 17+18=35) isotope 35.
argon
