john Dalton invented the atomic theory. John Dalton introduced the basic concepts on which the modern periodic table is based.
Atomic Mass
Plastics offer advantages over metal in weight, manufacturing costs, and corrosion resistance.
An isotope is any of the atoms of an element with different numbers of neutrons. It is determined by using the atomic weight,which is determined by the number of neutrons.
The Atomic Number of an element is equal to the number of Protons/Electrons in the nucleus and the Atomic Weight is approximately the total number of Protons/Electrons and Neutrons combined. Using Carbon as an example: Total Protons/Electrons = 6, therefore the Atomic Number is 6 Total Neutrons = 6, and the Atomic Weight is 12 Question? The Atomic Number of Lithium = 3 The Atomic Weight of Lithium = 7 How many Protons/Electrons? How many Neutrons? Answer: Protons/Electrons = 3 Neutrons = 4
By using experimental methods Dalton transformed Democritus ideas on atoms into a scientific theory.

The weight of neodymium (Nd), do you mean Atomic weight (mass) which can be check using Periodic Table of element. Atomic Number 60; Atomic weight 144.24; Density 6960 kg per m3 Hope this helps, using the term weight for an element without stating in what context, makes it difficult to know what answer is required.
Dalton viewed chemical change as the process of atom rearrangement. Using the atomic theory he came up with, he believed that chemical reactions rearranged the atoms into different combinations.

What is the advantage of using an PLM
by using certain mechanical objects, like a pulley, you can use the object's own weight to its advantage. Also, by exploiting gravity and the object's own weight, you can use inertia to roll the object down the hill or yet better in a free fall.
See the Web Links for "Answers.com: Atomic Mass" to the bottom for the answer. Atomic mass refers to the weight of an atom when compared to aribitary figure that is relative to other atoms.The unit used is 1/12 the weight of a carbon atom (the most prolific around). Atomic mass is used to avoid using very small numbers that would otherwise result if you try to physically weigh an atom.Note that atomic mass is not the same thing as atomic weight.
