Why do scientists use different types of models to represent compounds?
Why do scientists use different types of models to represent compounds?
A diagram that models the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule?
Lewis Dot Diagram. Most tests and reviews mostly look for simply the Lewis Diagram.
Why are atoms sometimes shown using models like the one in this picture?
There are different representations because different chemist discovered different things at different times. So all the different diagrams show what people at different periods in history thought and, as we find out more we are able to learn which idea is the most accurate.
Why are changes to the atomic theory necessary?
As atomic interactions occur on a molecular level, we cannot observe them. Hence the need to use atomic models. Atomic models can differentiate atom types, show us the structure of molecules and their bonding (ie. double-bonds, triple-bonds etc.) They can even show the angle of the bonds. However, they may not always be accurate and cannot show the strength of the bonds and conductivity etc.
How does Dalton's model of the atomic theory differ from the models that came before it?
You did not specify but seeing as my course is currently specifying in this field I have at least minimalist credentials in laments... Older models had electrons following an orbit which is frankly not true, modern day electron cloud models show that they are roughly here whereas for instance, the Bohr model shows them following a strict orbit
What are some limitations of models?
Some limitations of models are not to change what the model is asking you.
Why do models have limitations?
Models have limitations due to the fact that they are the real representation of the earth. Most of the scientific models are based on assumptions.
Why all models have limitations?
It depends on what you mean on limitations
Do all models have limitations?
false
What is a limitation to a model?
what are the limitations models
What are limitation of models?
Some limitations of models are not to change what the model is asking you.
What limitations do mathematical models have as problem solving tools?
There are many limitations that mathematical models have as problem solving tools. There is always a margin of error for example.
What does an electron dot structure model?
valence electrons
What are the advantages and disadvantages of using scientific models?
disadvantages *not to scale *there are limitations
Limitations of models?
Models only represent known possibilities for simulations. Models are limited by what a research determines will happen. A model can't demonstrate problems that are unknown.
What are limitations on models?
They're never perfect, and which errors they produce is seldom predicable.
What r 2 limitations of physical models?
The answer depends on what variable r stands for.
