Today's atomic model, primarily based on quantum mechanics, differs from earlier models by incorporating principles of wave-particle duality and probabilistic behavior of electrons. Unlike the Bohr model, which portrayed electrons as fixed orbits around the nucleus, the modern model describes electron positions in terms of probability clouds or orbitals. Additionally, advancements in technology have allowed for the visualization of atomic structures, reinforcing the concept of electron distributions rather than defined paths. Overall, the current model reflects a more complex and accurate understanding of atomic behavior.

How was mendeleevs periodic table like todays periodic table?
Mendeleev's periodic table arranged elements by increasing atomic mass and grouped elements with similar properties together. Today's periodic table is similar, but it is arranged by increasing atomic number, which reflects the number of protons in an atom's nucleus. Both tables also show periodic trends in properties as you move across and down the table.
How does bohrs model differ from todays?
Bohr's atomic model depicts the electron shells and orbitals as being two dimensional, staying the exact same distance away from the nucleus the entire time. Today, we know that electron orbits are three dimensional, and at best can only say where the electron in a given orbital is most likely to be at any given time, except for the f orbitals, as no one really knows for sure what those look like yet.
How do mendeelevs periodic table and todays periodic table differ?
When Mendeleev's periodic table was devised, some elements hadn't been discovered yet. Therefore, there had to be gaps in it or the table would be rendered incorrect. The rule of similarities states that the elements within a specific period/column are similar in a way and have the same number of electrons in the outer shell. E.g. Period 1 (alkali metals) react strongly with both air and water, have to be stored in oil, and are very alkali, hence the name. Mendeleev used this rule to construct the periodic table. The amazing thing is, he guessed where elements were missing and left gaps. He even estimated their atomic masses! In short, Mendeleev's periodic table had some bits missing. (e.g. technetium, discovered in 1936, a whole 65 years after Mendeleev's table was devised in 1871) P.S. It's Mendeleev, not Mendeelev.

She helped with the development of x-rays.
Why did people ignore Democritus idea for so long?
because he thought atoms were indivisble chunks of matter while todays science proves atoms can be divided into sub-atomic particles

Why is James Chadwick important in today's society?
James Chadwick is important in todays society because he discovered that atoms contained sub-atomic particles known as neutrons. This theory is accepted in the model structure of the atom in todays society

Is the 2007 proto pmr good?
well it all depends on what your definition of " good " is. you have to go further back into older models and acknowledge them. look at todays difference comapred to the older one, and also any other type off compoition models their are.
