Answer:
Calcium
Explanation:
The ability to be hammered into sheets is known in chemistry as malleability. One of the properties of metals is that metals are malleable. All metals thus have a common property that they can be hammered into sheets used in diverse applications. We can see diverse thin sheets of metals around us used to diverse purposes. This is a vary important property of metals that amplify its importance in materials science.
Of all the options listed, only calcium is a metal. Since nonmetals and metalloids can not be hammered into sheets, nitrogen, silicon and fluorine can not be hammered into sheets. Calcium, being a metal can be hammered into thin sheets.
Question:
Options
1) Nitrogen
2) Silicon
3) Fluorine
4) Calcium
Answer:
The correct option is;
4) Calcium
Explanation:
We analyze each of the elements as follows;
Nitrogen is a gas at room temperature, therefore it cannot be hammered into sheets
Silicon is a brittle non-metal, that breaks when struck
Fluorine is a gas at room temperature, therefore it cannot be hammered into sheets
Calcium is a soft, solid silvery-white, metallic element that is ductile, hence, it can be beaten into very thin sheets.
