Question

which of the following did dalton discuss in his atomic theory?
a. isotopes
b. ions
c. protons
d. electrons
e. neutrons
f. daltons theory did not discuss any of these topics.

Explanation:

Dalton's atomic theory proposed that all matter is made of atoms, which are indivisible and indestructible. It also stated that all atoms of a given element are identical in mass and properties. However, Dalton's theory did not discuss isotopes (atoms of the same element with different masses due to different numbers of neutrons), ions (atoms or molecules with a net electric charge), protons (positively - charged sub - atomic particles), electrons (negatively - charged sub - atomic particles), or neutrons (neutral sub - atomic particles). But the key point is that Dalton's theory was formulated before the discovery of sub - atomic particles and isotopes.

Answer:

F. Dalton's theory did not discuss any of these topics.
