Question

which of the following statements comprising Dalton's Atomic Theory is true even today ?

a. Matter consists of indivisible atoms

b. All the atoms of a given chemical element are identical in Mass and all other properties.

c. Atoms are indestructible.

d. Atoms retain their Identity in chemical reactions.

Answer 1

All the statements a. Matter consists of indivisible atoms.

b. All the atoms of a given chemical element are identical in mass and all other properties.

c. Atoms are indestructible.

d. Atoms retain their Identity in chemical reactions  

comprising Dalton's Atomic Theory are true even today.

Dalton's Atomic Theory:

• Dalton proposed a theory based on the atom's properties, mass, types, weight, and contents.
• It consisted of these contents where he studies that matter consists of indivisible atoms and hence cannot be divided.
• He also adds to the theory that atoms of an element are always identical in properties and mass.
• The other points in his theory also include the atoms retaining their identity while chemical reactions are indestructible in nature.

Answer 2

Answer:

All of the given statements comprising Dalton's Atomic Theory is true even today.

Explanation:

a. Matter consists of indivisible atoms.

• All of the existing matter in the universe is made up of a large number of atoms.

b. All the atoms of a given chemical element are identical in mass and all other properties.

• Every element is made up of atoms.
• The atoms that an element is made up of, are unique to that element.
• These atoms have identical properties that are unique only to that element.
• Atoms of different elements have different identical properties.

c. Atoms are indestructible.

• Atoms are the smallest unit of matter and cannot be divided further.
• There is no possible way to destroy an atom.

d. Atoms retain their identity in chemical reactions.

• The Law of Conservation of Mass states that the amount of mass before and after a chemical reaction must be the same.
• Hence, all atoms retain their identities in all chemical reactions.

Therefore, all of the given statements are true even today.
