a) Li or H
Interpretation:
The more electronegative element among Li and H is to be identified.
Concept introduction:
Electronegativity is the intrinsic ability of an atom to attract the shared pair of electrons in a covalent bond. Metals on the left side of the periodic table attract electron weekly and hence have low electronegativity values. Oxygen, nitrogen and halogens on the right side of the periodic table attract electron strongly and have high electronegativity values. The position in the periodic table determines the relative values of electronegativity of elements. The electronegativity generally decreases from top to bottom and increases from left to right across the periodic table.
To determine:
Which is more electronegative Li or H.
b) B or Be

A 1000 ppm Zn solution was prepared by dissolving the necessary amount of solid Zn(NO3)2 in water. The standards can be prepared by diluting the 1000 ppm Zn solution. Table 1 shows one possible set of serial dilutions (stepwise dilution of a solution) that Reagan could perform to make the necessary standards. Solution A was prepared by diluting 5.00 ml of the 1000 ppm Zn standard to 50.00 ml. Solutions C-E are called "calibration standards" because they will be used to calibrate the atomic absorption spectrometer.
