To create a 3-D model of an atom, a student can use wire, wire cutters, fishing line, various colors of marshmallows and bamboo skewers to manufacture the atom. The marshmallows can represent the neutrons, protons and electrons, while various lengths of wire are used to create electron clouds.
Making a 3-D model is simple, requiring few steps.
Step 1: Decide what each marshmallow depicts
Each atom component is a different color. The protons and neutrons are strung together using fishing line to make the nucleus.
Step 2: Use the wire cutters to create the correct amount of electron clouds.
Once all of the electron clouds are present, electrons should be placed into the appropriate cloud.
Step 3: Connect all of the components using bamboo skewers.
The electron clouds are connected so that they surround the nucleus.Learn More
A Bohr model of Yttrium is a representation of an atom of Yttrium. Yttrium was discovered by Johann Gadolin in 1794. It is named after a town in Sweden.Full Answer >
The electron cloud model is a theory of the atom that comports with the modern understanding of quantum mechanics. The model dispenses with the classical "orbiting electrons" depiction and envisions electrons as holding indeterminate positions in a diffuse cloud around the nucleus of the atom.Full Answer >
Democritus' model of the atom was simply a round, solid ball. Democritus knew nothing of separate protons, neutrons and electrons; all he knew was that everything physical was composed of atoms, according to Boise State University. Democritus concluded, "Nothing exists except atoms and empty space."Full Answer >
To draw a Bohr model of an atom, first find the number of protons, neutrons and electrons in the atom from its atomic weight and atomic number. After that, place the neutrons and the protons in the nucleus, and draw the electrons in their designated shells.Full Answer >
