Question
Chapter 3, Problem 3.49E
Interpretation Introduction
Interpretation:
The trend of density of the metallic elements on moving from left to right across a period of the periodic table is to be predicted.
Concept introduction:
Density is defined as the ratio of mass of a substance to its volume. Mass number is defined as the sum of number of protons and neutrons which are also known as nucleons.
On moving from left to right in a periodic table, the atomic radii decrease. On the other hand, the atomic radii increase from top to bottom.

Some of these techniques are:Distillation – this process is used to separate components that have significantly different boiling points. The solution is heated and the lower boiling point substance is vaporized first. The vapor can be collected and condensed and the component recovered as a pure liquid. If the temperature of the mixture is then raised, the next higher boiling component will come off and be collected. Eventually only non-volatile components will be left in the original solution.Centrifugation – a centrifuge will separate mixtures based on their mass. The mixture is placed in a centrifuge tube which is then spun at a high speed. Heavier components will settle at the bottom of the tube while lighter components will be at the top. This is the technique used to separate red blood cells from blood plasma.Sieving – this is…arrow_forwardBriefly describe a eutectic system.arrow_forward
