How does the current model of the atom differ from j.j. thomsons model

hodyreva [135]

Thomson's model of the atom was called the plum pudding model. He discovered electrons, so he placed them in the atoms. This was before the nucleus was discovered.

Now, the current model is an atom that contains a positively charged nucleus (with both protons and neutrons), and negatively charged orbitals with electrons.

A mixture contains 20% iron ions by mass. What mass of iron chloride (FeCl) would

omeli [17]

Mass of iron chloride (FeCl₂) : 22.68 g

<h3>Further explanation</h3>

Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements

In the same compound, although from different sources and formed by different processes, it will still have the same composition/comparison

With this law, we can calculate how many grams an element is needed to make a compound with a certain mass, as desired

<h3 />

$\tt mass~Fe=\dfrac{Ar~Fe}{MW~FeCl_2}\times mass~FeCl_2$
