Which one of the following is an ion? He
14C
NaCl
B3+
He -it is a neutral atom without any charge
C-14 -This one also neutral atom
NaCl- is an ionic compound total charge on the molecule is zero
B3+ -this one has 3+ charge that means 3 electrons have been
lost from'the Boron atom
Since it has apositive charge,it is called cation
Answer B3+
thank you

1) when you have 2.0M solution of NaCl, what is the molarity of Na+ ion and Cl- ion? 2) If you have 2.0M solution of CaCl2, what is the molarity of Ca2+ and the molarity of CI-ion in this solution? 3) Comparing molarity of Cl-ion in 2.0M NaCl solution and 2.0M CaCl2 solution, which solution has more CI-ion? 4)Give formula of the two ions exist in a solution of 0.10M of AI(NO3)3 ? what are their respective ion concentrations?
In nacl molecule, the interaction potential between na ion and cl ion fits the following equation: V(r)=-e2/r+ α.e-r/q in this equation, the first term hammer is the coulomb potential,the second term results from the distribution of other electrons in the system. The equilibrium position between the two ions is where the potential is minimum: f(r)=-dV/dr=e2/r2- α/q . e-r/q =0 the root of this equation gives the r0 bond length.experimental for NaCl α=1.09*103 eV,q=0.33 A and e2 =14.4 A eV Write the c...

A 0.500 g sample of AgCl was mixed with 250 mL sodium chloride solution of unknown molarity. In order to find the molarity of sodium chloride the amount of dissolved silver ion was monitored with an ion selective electrode at 25 C. The electrode registered the concentration of Ag+ ion to be 3.75x10^-8 M. Calculate the concentration of molarity of the NaCl.
