We know that for a single electron system Bohr's atomic model is able to predict the binding energy levels quite accurately. As such using the formula for a nucleus with Z protons, the …

Rutherford could only account for these phenomena by proposing an atomic model in which MOST of the atom was EMPTY space, and a small, massive, nuclear core contained most of …

The Plum Pudding model stated that atoms are positive spheres with randomly placed negative Electrons. By defining the location of the positive and negative charges, this model was easily …

The periodic table of elements is an amazing classification tool. There are many things that we chemists do which only require a quick glance at the table to obtain the answer we require. …

See. 1.Explain Rutherford's atomic postulates? 2. Who discovered proton and electron? 3.Which assay was done by Rutherford? 4.What was the breadth of the gold foil used in Rutherford …

Nov 29, 2015 · It didn't prove anything; it provided good evidence against, and good evidence for a particular model of atomic structure. See here and elsewhere.

Big rip: This model says that dark energy will continue grow stronger with time and cause the expansion to accelerate. Such an event will cause large bodies like galaxies to recede from …

May 15, 2017 · 36 neutrons. One way we have of differentiating between various nuclides of the same element is by writing the name of the element followed by a hyphen and the mass …

Feb 5, 2017 · The presence of different numbers of neutrons for a given atomic number, explains the existence of isotopes, and the quoted atomic mass is the average of the individual isotopic …
