why are the elements on the periodic table not arranged by mass?

a. similar elements have such different masses that this would lead to a completely random arrangement of elements.
b. atoms are so small that it would make little sense to talk about their masses.
c. this would not allow all of the elements with similar properties to be lined up with each other.
d. atoms with similar masses are so different from each other that this would lead to a random arrangement of atoms.​

Answer :

Answer:

Its actually:

c. this would not allow all of the elements with similar properties to be lined up with each other.

This is because similar elements have such different masses that this would lead to a completely random arrangement of elements.​

Explanation:

  • The elements in the periodic table are arranged in increasing order of the atomic numbers
  • This is so because the chemical properties of elements depend upon the number of electrons.
  • The number of electrons in two different atoms can never be the same.
  • The atomic mass of the two different elements can be the same. Due to which the arrangement of elements in a periodic table would have become complicated.

       For example, Argon and calcium both have an atomic mass of 40 but the former is noble and the latter is metal.

So, from this, we can conclude that elements in the periodic table are arranged by mass because similar elements have such different masses that this would lead to a completely random arrangement of elements.​
