C18H18 is the molecular formula for a symmetrical alkane known as n-octadecane. When building a model of n-octadecane, it may appear as a straight chain due to the fact that the carbon atoms bond in a linear fashion. However, due to the nature of molecular geometry and atoms in 3D space, the model may twist or bend slightly, deviating from a perfectly straight line.
just took the test
The correct molecular formula for C7H16 is heptane, which is a straight-chain alkane hydrocarbon with seven carbon atoms and sixteen hydrogen atoms.
To build a 3D model of scandium, you would first need to determine the correct number of protons, neutrons, and electrons in a scandium atom (Z = 21). Then, you can represent these particles in a 3D software program using spheres (for protons and neutrons) and smaller spheres or dots (for electrons) arranged in the correct configuration within the atom. Finally, you can use the software's tools to connect these particles with lines that represent the bonds between them to create a 3D model of the scandium atom.
J.J Thompson discovered the electron during his famous cathode ray tube experiment in 1897, but it was actually Niels Bohr who discovered the electron shell (by accident), performing an x-ray experiment in 1909.
When the number of electrons does not equal the number of protons, the atom is ionized. (The atom is then called an ion).
You build it.
at cassy's model and art compannies or i will build a model for you
You can build a model airplane, model auto or an arrow.
With model wood!
Need serial # for build date & location, not model #.
No. The Model A began in 1927.
How do you build a working model of science and technology for games and sports?
well you would just build it
you can build it out of anything if you are smart
i did it with paper
== ==
With a hammer
