atomic number = protons.

protons+neutrons=atomic mass.

170 (mass) - 41 (proton/number) = 129

that should be ur answer. I hope this helps!

Rama09 [41]

The question is not complete. Proposed completed question is:

When aqueous solutions of sodium chloride and silver nitrate are mixed, a double-displacement reaction occurs.  What is the balanced equation for the reaction?

               A.  

NaCl(aq) + AgNO3(aq) --------NaNO3(aq) + AgCl(aq)

               B.  

NaCl(aq) + AgNO3(aq) -------- NaNO3(aq) + 3AgCl(s)

               C.  

NaCl(aq) + AgNO3(aq) --------- NaNO3(aq) + AgCl(s)

               D.  

NaCl(aq) + AgNO3(aq) --------- Na(s) + AgNO3Cl(aq)

               E.  

NaCl(aq) + AgNO3(aq) --------- NaNO3(aq) + ClAg(s)

Answer is

       A.  

NaCl(aq) + AgNO3(aq) --------NaNO3(aq) + AgCl(aq)

Explanation:

Following the law of conservation of energy, the total number of atoms in the reactant  side is equal to the total number of atoms in the product side.

The arrangement of elements based on their properties
Thepotemich [5.8K]
<span>The arrangement of the periodic table leads us to visualize certain trends among the atoms. The vertical columns ( basically their groups) of the periodic table and they are arranged such that all its elements have the same number of valence electrons. And all the elements within a certain group thus share similar properties and that's about it.</span>
