Which of the following lists the elements in order of increasing malleability?

Chemistry

Answer:

The correct option is: <u>A. Se, Sb, Sn  </u>            

Explanation:

Malleability is the physical property of a chemical element, that allows it to change its shape or form thin sheets, when pressure or stress is applied.

It is a characteristic property of a metal. Mettaloids and non-metals are not malleable in nature, as they are brittle.

Since, Selenium (Se) is a non-metal, it is <u>non-malleable</u>.

Antimony (Sb) is a metalloid, it is <u>non-malleable.</u>

Tin (Sn) is a metal, it is <u>malleable.</u>

Therefore, <u>the increasing order of malleability </u>is: <u>A. Se, Sb, Sn</u><u>.</u>

The answer would be (B) Sb, Sn, Se.

The periodic table may look like a confusing checkerboard of elements, but they are categorized in more ways than you may know.

For malleability, we look for metals. Metals/metallic elements have characteristics like electrical conductivity, <u>malleability</u>, ductility, and other physical characteristics like luster. The more an element is metallic, the more of these characteristics it will have.

So to answer this question, you simply have to see what kind of elements these are:

Sb, 51 (Antimony): <em>Metalloid</em>

Sn, 50 (Tin): <em>Transition Metal</em>

Se, 34 (Selenium): <em>Non-Metal</em>

Therefore, Antimony will have more metal characteristics than the rest, putting it at the top. Selenium is a non-metal, so that goes at the bottom, and Tin will be second.

a mixture consisting of only of lithium chloride, lithium carbonate, and lithium nitrate was analyzed
Dafna11 [192]

A mixture consisting of only of lithium chloride, lithium carbonate, and lithium nitrate was analyzed by the help of concentric hydrochloric acid.

<h3>What is concentric hydrochloric acid?</h3>

The concentric hydrochloric acid is used for the analysis of organic and inorganic mixture like  lithium chloride, lithium carbonate, and lithium nitrate it releases fumes and cannot be touched with normal hands.

Always use a dropper to use it and for the chemical analysis.

Therefore, mixture consisting of only of lithium chloride, lithium carbonate, and lithium nitrate was analyzed by the help of concentric hydrochloric acid.
