Question

(u3:1) build an atom - phet virtual lab
learning goals: review of atoms
★ using the build an atom simulator, i can identify the various subatomic particles in an atom and their relative location in the atom. i can identify (and compare/contrast) the properties an atom and what particles affect this. i can use incomplete given information to build a complete atom

? overall big question: what is an atom, what is it made of, and what does this composition mean for the atom?
★ pre - lab questions: answer to the best of your knowledge
? what is an atom? explain.
? what do you think the is difference between an atom and an element? explain your thinking.
★ set - up directions:
□ access the build an atom
build an atom
scan the qr >
□ click the box that says “atom.”
□ check the “stable/unstable” box in the lower right corner.
□ click the green + to the right of “net charge” and “mass number” so that it will show you the maximum amount of information
□ set - up should match the screenshot before moving on!
★ part one: atomic basics
✸ atoms are made up of subatomic (means smaller than an atom) particles. these particles are placed along the bottom!
? based on the simulator what are the three subatomic particles that make up an atom?
□ now attempt to drag these particles from the buckets onto the simulator to see where the simulator allows you to put them.
? list the subatomic particles that you can place in the nucleus:
? list the subatomic particles that you can place in the orbitals:
? big question: are there any particles that you can place in both areas (the orbits and the nucleus).

Explanation:

An atom is the basic unit of matter. It consists of a nucleus containing protons and neutrons, surrounded by electrons in orbitals. An element is a pure substance made of only one type of atom. The three sub - atomic particles are protons (positively charged), neutrons (neutral), and electrons (negatively charged). Protons and neutrons are placed in the nucleus, while electrons are in the orbitals. No particle can be placed in both the nucleus and the orbitals as they have distinct locations and properties within an atom.

Answer:

• What is an atom? An atom is the fundamental unit of matter, composed of sub - atomic particles including protons, neutrons, and electrons.
• Difference between an atom and an element: An element is a pure substance made up of only one type of atom. An atom is the basic building block, while an element is a collection of the same type of atoms.
• Three sub - atomic particles: Protons, neutrons, electrons.
• Sub - atomic particles in the nucleus: Protons, neutrons.
• Sub - atomic particles in the orbitals: Electrons.
• Particles in both areas: No.
