Question
Among the following, the element possessing a low melting point is
- Metals
- Non-metals
- Metalloids
- None of the above
Hint:
The element with the lowest melting point is the one that has the highest atomic number.
The correct answer is: Non-metals
- The element possessing a low melting point is Non-metal.
- Non-metals that form discrete molecules have low melting points. This is because the intermolecular attraction is only about 5-10% of the strength of a covalent bond. Examples include oxygen, nitrogen, fluorine, white phosphorus, sulfur, and chlorine.
- Non-metals that form network solids have higher melting points because covalent bonds must be broken in order to melt. Examples are boron, carbon, and silicon, not to mention germanium.

Which of the following is a property of a non-metal?
The correct option is b)Is brittle and breaks easily
Metal is malleable and can be hammered into a plate. Gold, silver, aluminum and tin can be pounded into very thin sheets called foils. Non-metals do not have malleable properties. Non-metals are not malleable or elastic. It has a dull sheen, whereas iodine has a sheen. Examples of non-metals include carbon, oxygen, sulfur, phosphorus, etc.

This group of elements has properties that are opposite those of metals. ______________________
The correct option is b)Non - metals.
Non-metals are natural materials which do not generate heat or electricity and are structurally fragile (that is, they cannot be easily rolled, shaped, extruded, or pressed). Hydrogen, carbon, nitrogen, oxygen, phosphorus, arsenic, and selenium are non-metallic elements on the periodic table.
