Zinc atomic symbol: Zn, atomic number: 30 is a Block D, Group 12, Period 4 element with an atomic weight of The number of electrons in each of zinc's shells is 2, 8, 18, 2, and its electron configuration is [Ar] 3d 10 4s 2.

The zinc atom has a radius of pm and a Van der Waals radius of pm. Zinc was discovered by Indian metallurgists prior to BC and first recognized as a unique element by Rasaratna Samuccaya in Zinc was first isolated by Andreas Marggraf in In its elemental form, zinc has a silver-gray appearance. It is a fair conductor of electricity, and burns in air at high red producing white clouds of the oxide.

Zinc is mined from sulfidic ore deposits. It is the 24th most abundant element in the earth's crust and the fourth most common metal in use after iron , aluminum , and copper. The name zinc originates from the German word "zin," meaning tin. Zinc triflate catalyzed 1,3-indolylation of cyclohexanones: tandem condensation, dehydrogenation and aromatization sequence. Copper substituted zinc ferrite with abundant oxygen vacancies for enhanced ciprofloxacin degradation via peroxymonosulfate activation.

To measure the density of a sample of a substance, it is necessary to measure its mass and volume. Mass is typically measured using an analytical balance, a precise instrument that relies on the force exerted by the sample due to gravity.

The container to hold the sample also used to measure volume is weighed and tared, so only the sample mass appears on the balance display when the sample is added to the container. For liquids, this container is typically a volumetric flask, which has one marking that corresponds to a specific volume. The container is filled to the line with the liquid sample and weighed again after the empty flask has been tared.

The measured density is the ratio of the measured mass to the volume indicated on the flask. Most solid substances are irregularly shaped, which complicates volume determination. It is inaccurate, for example, to determine the volume of a powder by measuring its dimensions. Instead of directly measuring dimensions or using glassware like a volumetric flask, it is necessary to make use of a liquid displacement method to measure the volume of an irregularly shaped solid.

A graduated cylinder containing a known volume of liquid in which the solid is insoluble is tared. The solid is added to the cylinder, and the total mass is weighed again to determine the mass of the solid. Addition of the solid causes an upward displacement of the liquid, resulting in a new volume reading. The volume of the solid is equal to the change in volume due to liquid displacement i. As for liquids, the measured density of a solid sample is the ratio of the measured mass to the measured volume.

This video will introduce the principles of density determination, the procedures for calculating the density of both solid and liquid substances, and some applications of density in scientific research.

However, the volume of space occupied by the same mass is different for different substances, depending on their respective density. For example, a ton of bricks has the same mass as a ton of feathers, but occupies considerably less volume. Density is obtained by dividing mass by volume.

Mass can be measured with scales or balances, and is expressed in grams or kilograms. By convention, the volume of liquids and gases is often expressed in units of liters or milliliters, measured with glassware. The dimensions of regularly shaped solids can be measured directly with rulers or calipers, which have linear units, giving volumes in units such as cubic centimeters.

One milliliter is equivalent to one cubic centimeter. The dimensions of irregularly shaped solid samples cannot be easily measured. Instead, their volumes can be determined by submerging the solid in a liquid. The volume of the submerged solid is equal to the volume of liquid displaced. Now that you understand the concept of density, let's take a look at two protocols for accurately determining the density of a liquid and a solid.

To begin this procedure, place a clean and dry mL volumetric flask on an analytical balance. After the measurement has stabilized, tare the balance. The balance should read zero. Use a funnel to add approximately 45 mL of liquid to the flask. Do not fill to the calibration mark. Use a Pasteur pipette to carefully add the final 5 mL of liquid, just until the bottom of the liquid's meniscus touches the line on the flask. Weigh the flask again and record the mass of the liquid.

Repeat the measurements at least twice to obtain additional values to calculate an average density. The results are shown in this table. The average measured density was 0. To determine the density of an irregular solid in pellet form, add approximately 40 mL of water to a clean and dry mL graduated cylinder. Record the exact volume. Place the cylinder on an analytical balance and tare. Add approximately 10 pellets, and record the new volume after the addition.

Weigh the cylinder, water, and pellets. The mass is only the pellets, as the rest have been tared. Make at least two additional sets of mass and volume measurements to calculate an average value of the density.

The density for zinc was measured for three different samples. It was found to be 6. Note that, since the measurements were made in a graduated cylinder, which is less precise than a volumetric flask, the density has lower degree of precision.

Let's now look at several different applications of density to different field of scientific research. Density is useful for identifying or validating pure materials, such as elements or other species of known purity.
