Based on Reference Table S, the atoms of which of these elements have the strongest attraction for electrons in a chemical bond?
BabaBlast [244]
Answer is (1) - N

<em>Explanation:</em>

I think the given chart is electronegativity chart.

Electronegativity is a value that tells us how an atom can attract electrons towards itself. <span><u>If the electronegativity is high, then the attraction to the electrons is high unless the attraction to the electrons is low. </u>

Electronegativity increases from left to right of the periodic table and decreases from up to down. 
Hence, highest electronegative atom is F which has 4.0 and lowest electronegative atoms are Cs and Fr (0.7).

The electronegativity values for given atoms are
  N - 3.0
  Na - 0.9
  P - 2.1
  Pt - 2.2 </span>

You will start this experiment with 25 mg of the trans isomer. What is the percent yield if you obtain 5 mg of the cis isomer?
USPshnik [31]
Isomers have the same molecular formula but they only differ in structure. So, when trans isomer is converted to cis isomer, you would expect a total mass of 25 mg exactly. So, the percent yield would be:

Percent yield = 5 mg/25 mg * 100 = <em>20%</em>
