QUESTIONS WITH CORRECT ANSWERS 2026
What concept includes allotropes? - CORRECT ANSWER -
*An element exhibits allotropy when it can exist as two or more distinct chemical structures.
*For example: the three allotropes of carbon, graphite, diamond, and C(60) (buckminsterfulleren
e).
*No all elements have allotropes.
What is an amorphous substance? - CORRECT ANSWER -*Amorphous means without structure.
*Amorphous substances have no long-range crystal structure.
*Glass, chocolate, pudding, and cotton candy are examples of an amorphous substance.
Amphoteric -ECORRECT ANSWER -
A substance that can both donate and accept protons. Example: H(2)PO(4)-
Amphiprotic - CORRECT ANSWER -
A substance that can react as both an acid and a base. Example: Al(2)O(3)
What is the concept behind the atomicEnumber? - CORRECT ANSWER -
* The atomicEnumber is the number that specifies the position of an element in the periodic tabl
e.
* It is also a number representing the number of protons in the nucleus of an atom.
The atomic number defines the identity of an element.
The basic idea is that each element must fall in some sort of order. Mendeleev originally based th
e order on atomic masses. It was later found that the order should be based on the number of pr
otons in the nucleus of an element.
