Obviously models are alot bigger and made of plastic most likely, generally being hydrocarbon as opposed to the element that is to be represented in the molecule.
Also with molecular models, you just see one "ball" for an atom. However, you do not see the nucleus and electrons and the full flexibility of the bonds
xenon is generally unreactive. How is its low reactivity related to its position in the Periodic Table?
No. A model is simply that. A model is how we describe reality in a a way that helps us make meaningful predictions as to what might happen.
No, the atomic mass is the average mass of the atom and the atomic diameter is the average diameter of the atom
No.
There are a few reasons why Thomson's atomic model failed. It did not consider the reasoning behind atomic reactions or neutrality. It was just a visual he created with electrons placed haphazardly on a proton base. That arrangement is why it is commonly known as the plum pudding or raisin bun model.
28. Atomic mass - Atomic # (same as the number of protons) = number of neutrons
In a neutral atom, the number of electrons is always the same as the atomic number.
The current model of an atom is called the Bohr model.
No. A model is a bigger or smaller version of the actual thing, in this case the model is bigger than the real thing.
no
Yes. It is true. An atom with a different atomic number is an atom of a different element.
Atomic number of a atom is same as the number of protons of the same atom
No, the atomic mass is the average mass of the atom and the atomic diameter is the average diameter of the atom
No.
This is the definition of an "isotope".
the atomic number
The atomic number of the cation is the same as the atomic number of the neutral atom.
