The factors responsible for the ionization enthalpy of the main group elements to decrease down a group are listed below: (i) Increase in the atomic size of elements: As we move down a group, the number of shells increases. As a result, the atomic size
These currencies are less likely to yield high returns in a short time because they are not very volatile. To sum things up, these three currencies are the core safe haven choices in this asset class. Although they are still subject to volatility and inflation, they have historically outperform...
usually by oxidizing the surface of the electrode material, whereas non-electrolytic (often called “electrostatic” capacitors) use dielectric materials that are generally formed through various mechanical processes and are not a chemical derivative of the electrode material itself. This...
Precious metals are heavy. Just below is a chart comparing the original eight. Iridium and osmium are the densest known terrestrial substances at 22.56 and 22.59 grams per cubic centimeter. That’s twice the density of lead or about 8 times that of granite. A cube 6 inches on a side (15...

So, for example, the red column on the right contains the Noble Gases (helium, neon, argon, krypton, and so on), which are relatively unreactive. The pink column on the left contains the alkali metals (lithium, sodium, potassium, and so on), which are relatively reactive metals (you ...
There are three such associations of priests, and one of women, called oblates. Oblate (a.) One of the Oblati. Oblateness (n.) The quality or state of being oblate. Oblati (n. pl.) Children dedicated in their early years to the monastic state. Oblati (n. pl.) A class of ...

As a result, they are chemically stable and do not typically form bonds with other elements. - Therefore, the valency of monoatomic gases, specifically noble gases, is zero. Final Answer: - A monoatomic gas is Helium (He), and its valency is zero. --- Show More ...
