Q15: |
What were the characteristics of Dalton's model of the atom? |
Adriana |
9/9/2007 |
Ans: |
All matter consists of made up of tiny indivisible particles called atoms. Atoms are indestructible and unchangeable by chemical or physical changes. Elements are characterized by the mass of their atoms. The atoms of an element are identical. Elements react to form compound (s) their atoms combine in simple, whole number ratios; there could be more than one ratio to form multiple compounds. In a given compound, the relative number and kind of atoms are constant. |

Q17: |
were there any drawbacks of dalton theory? |
kim |
19/8/2007 |
Ans: |
Dalton’s model fell short on many counts to fully explain the atomic model like Similarity of elements in a particular group, what was the cause of compound formation, emission spectra etc. This led to modification in the Dalton’s model, however this does not discount the brilliant work of a scientist that was way ahead of its time and laid the foundation of atomic theory. |

Q19: |
How did Dalton discovered Law of Multiple Proportion? |
Lourd Arnie Amores |
22/11/2006 |
Ans: |
Briefly, Dalton’s work was influenced by Proust’s law of definite proportion and his own study of partial pressure of gases as a metrologies and later through his experiments, as per his lab notebook it was as early as 1802 that started thinking in that line and in the paper on “Proportion of the gases or elastic fluids constituting the atmosphere”, he had established the basis and later in 1805 finally produced a paper on law of multiple proportion. |
