5 physical properties of osmium
lisabon 2012 [21]
In 1803AD, Osmium was discovered by Smithson Tennant when dissolving an impure sample of platinum in aqua regia, a mixture of hydrochloric and nitric acids. He was able to determine that the black powder left behind after dissolving the platinum was actually a mixture of two new elements, indium and osmium.

•Osmium is a bluish-white and shiny metal.

•Osmium is very hard and is brittle even at very high temperatures.

•Osmium has the lowast vapor pressure and the highest melting point among the platinum group of metals.

•Osmium's density is slightly more than iridium hence is credited as the heaviest element.

How many electrons in an atom can have the following quantum
gavmur [86]

The answer for the following question is explained.

<u><em>Therefore the  number of electrons present with the values n = 5, l = 2, m = -2, s = +1/2 is</em></u><u> </u><u><em>one(1).</em></u>

Explanation:

Here;

n represents the principal quantum number

l represents the Azimuthal quantum number

m represents magnetic quantum number

s represents spin quantum number

n = 5,

l = 2,

m = -2,

s = +1/2

Here, it implies 5d orbital.

In the  5d  orbital, 10 electrons.

As the magnetic quantum number is -2, and so it can have 1 electron.

<u><em>Therefore the  number of electrons present with the values n = 5, l = 2, m = -2, s = +1/2 is</em></u><u> </u><u><em>one(1)</em></u>

FrozenT [24]
A colloid has the particles that have the ability to scatter light called the Tyndall effect named after the scientist named Tyndall. A suspension has large suspended particles that settle out at the bottom of the container. A solution has small particles that are evenly distributed throughout. Hence the answer is choice 2.
