Chemistry of Metals and Alloys Questions

Multiple choice

The metals having outstanding catalytic properties are

  1. the alkali metals

  2. the alkaline earth metals

  3. refractory metals

  4. the platinum metals
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The platinum group metals is a term used sometimes to collectively refer to six metallic elements clustered together in the periodic table. These elements are all transition metals.The platinum metals have outstanding catalytic properties. They are highly resistant to wear and tarnish, making platinum, in particular, well suited for fine jewellery. Other distinctive properties include resistance to chemical attack, excellent high-temperature characteristics, and stable electrical properties.

Multiple choice

The ferrite characterised by needle shaped crystallites is

  1. acicular ferrite

  2. ausferrite

  3. martensite

  4. zinc ferrites
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Acicular ferrite is a microstructure of ferrite that is characterised by needle shaped crystallites or grains when viewed in two dimensions. The grains, actually three dimensional in shape, have a thin lenticular shape. This microstructure is advantageous over other microstructures because of its chaotic ordering, which increases toughness.

Multiple choice

Brass is an example of

  1. an alloy

  2. a compound

  3. a mixture

  4. an element
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

An alloy is a material composed of two or more metals or a metal and a nonmetal

Multiple choice

Which of the following is an element?

  1. Water

  2. stean

  3. snow

  4. iron
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

An element is a substance consisting of atoms which all have the same number of protons - i.e. the same atomic number. Elements are chemically the simplest substances and hence cannot be broken down using chemical methods. Elements can only be changed into other elements using nuclear methods.

Multiple choice

Which of these elements is not a metalloid?

  1. Tungsten

  2. Germanium

  3. Bismuth

  4. Antimony
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A metalloid is a chemical element with properties in between, or that are a mixture of, those of metals and non - metals
