They are neutral.
its either positive or neutral
The oxidation number of Cr in Cr3+ is +3. This is because each Cl ion has a charge of -1, and since the compound is neutral, the total positive charge from Cr must equal the total negative charge from the Cl ions.
There are no atoms in NaCl . (Sodium Chloride) . They are all combined together as ions. Na^(+) & Cl^(-) The ratio of positive ion to negative ions is 1:1 NB An atom is an neutral (uncharged) species. An ion is an atom that has lost or gained electrons, and thereby becoming a charged species.
Na+ and Cl- are spectator ions.
The compound formed when Na+ and Cl- are combined is called sodium chloride (NaCl).
Because the sodium chloride salt has equal amount of Na+ and Cl-. NaCl has the relation of 1:1. This is the reaction that happens when you dissolve NaCl in water: NaCl <---> Na+ + Cl- As you can see equal amount of positive and negative ions is formed.
The water solution of sodium chloride is neutral; the solid NaCl is neutral. After dissociation are formed the cation Na+ and the anion Cl-.
Sodium Chloride does not have free electrons normally, Sodium with electron arrangement: 2,8,1 and Chlorine with electron arrangement: 2,8,7 When they react Sodium ionises to 2,8 ( Ne) Chlorine gains the free electron to ionise to 2,8,8 (Ar) Forming Sodium Chloride or Na+CL-
When sodium (Na) and chlorine (Cl) combine to form a neutral compound, they undergo ionic bonding. Sodium loses one electron to become a positively charged ion (Na⁺), while chlorine gains that electron to become a negatively charged ion (Cl⁻). These oppositely charged ions attract each other and form sodium chloride (NaCl), commonly known as table salt, resulting in a neutral compound overall due to the balance of positive and negative charges.
the formula for Na positive and Cl negative is NaCl.Commonly called as table SALT
Cl- in aqueous solution is neutral, but according to Lewis theory it is base because it is electron donor. you can learn more on wikipedia: http://en.wikipedia.org/wiki/Lewis_acids_and_bases
