Multiple choice chemistry metals physical properties of metals and non-metals some physical properties of metals general characteristics and uses of metals

Which of the following metal is famous with magicians for its melting properties?

  1. Tellurium

  2. Gallium

  3. Dysprosium

  4. Rhodium
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Gallium is a metal with lowest melting point. When we hold it and apply pressure with fingers, It melts at room temperature because of low melting point so, it is used by magicians.

Which one of the following four metals would be displaced from the solution of its salt by other three metals?

  1. Mg

  2. Ag

  3. Zn

  4. Cu
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Ag metal would be displaced from the solution of its salt by Mg, Zn or Cu metals.

Among the given metals, the standard reduction potential for the half reaction $\displaystyle Ag^+ + e^- \rightarrow Ag$ is maximum.

Hence, among the given metals (ions),  $\displaystyle Ag^+ $ ion has maximum strength as oxidising agent. Hence, $\displaystyle Ag^+$ ion gains an electron and other metals loses electron.

Which of the following is non-ductile?

  1. Selenium

  2. Copper

  3. Aluminium

  4. Magnesium
Reveal answer Fill a bubble to check yourself
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.

Boojho has learnt that non-metals on beating with a hammer are generally broken into pieces. Which of the following is a non-metal?

  1. Iron nail

  2. Aluminium wire

  3. Copper plate

  4. Piece of coal
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All are metals in the given options iron, aluminium and copper but only carbon is a nonmetal present which is breakable with a hammer.

Iodine is a non-metal which has metallic lusture.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Its because going down the group the size of the atom increases because of shielding effect due to which the interaction between the atom and the outermost electron decreases so these electrons on the surface of iodine become excited by absorbing heat energy from light so when they release this energy and come to their normal state, they emit this light so it appears that they have lustrous surface.
