A Correct answer
Explanation

Selenium is a chemical element with symbol Se and atomic number 34. It is a nonmetal with properties that are intermediate between those of its periodic table column-adjacent chalcogen elements sulfur and tellurium. As it a non-metal, it cannot be deformed into a wire as it is brittle.

Which of the following is not a property of non-metals?

  1. Non-metals can be stretched into thin wires

  2. Non-metals are not ductile

  3. Non-metals are not malleable

  4. Non-metals break easily

A Correct answer
Explanation

Non-metals are non-malleable and non-ductile. They are brittle. They break easily. So, they are regarded as brittle. They can't be stretched into mines or hammered into sheets.

______________ is the non-metal which conduct electricity.

  1. Carbon

  2. Nitrogen

  3. Oxygen

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

Carbon is the non-metal which conduct electricity in the form of graphite which is it's allotrope. Allotropes are the compound of the element in which they have same chemical properties but different physical properties.
