Atoms are made of three subatomic particles - protons, neutrons, and electrons. The atom has two main parts - the nucleus and the orbits (which are also called the electron clouds)
Drag a proton onto the atom. Where does it go?

Drag a neutron onto the atom. Where does it go?

Drag an electron onto the atom. Where does it go?

What subatomic particles (protons, neutrons, and/or electrons) are found in the nucleus of an atom?

What subatomic particles (protons, neutrons, and/or electrons) are found in the obits?

What element did you make when you added one proton, one neutron, and one electron?

Add another proton to the atom that you made. What changes?

Add another neutron to the atom that you made. What changes?

Add another electron to the atom that you made. What changes?

What subatomic particle (proton, neutron, or electron) is responsible for determining the identity of an atom?

What subatomic particles (protons, neutrons, and/or electrons) are responsible for determining the mass number of an atom?

What subatomic particles (protons, neutrons, and/or electrons) are responsible for determining the net charge of an atom?

Part II - Building Atoms of Elements
Build the following atoms of elements. When each one is complete, record the protons, neutrons, and electrons in it, determine the identity of the element, and use colored pencils or markers to draw it on the model given.

Atoms, Elements, & the Periodic Table

BUILD AN ATOM INTRO

Part I - Explore the Atom

  1. Adding Protons, Neutrons, and Electrons:

    • When I dragged a proton onto the atom, it went right into the nucleus, which is the central part of the atom.
    • I dragged a neutron onto the atom, and that also went into the nucleus, just like the proton.
    • When I dragged an electron onto the atom, it went into the orbits or electron clouds surrounding the nucleus.
  2. Subatomic Particles in Different Locations:

    • The subatomic particles found in the nucleus of an atom are protons and neutrons.
    • In the orbits, there are the electrons.
  3. Identifying the Element:

    • When I added one proton, one neutron, and one electron, I made Hydrogen (H).
  4. Changes When Adding More Particles:

    • Adding another proton changed the atom to Helium (since it has 2 protons now).
    • Adding another neutron to the original atom mostly changed its mass but kept it as Hydrogen.
    • Adding another electron changed the net charge, making it a negatively charged ion.
  5. Determining Factors for Atoms:

    • The subatomic particle that determines the identity of an atom is the proton.
    • Protons and neutrons determine the mass number of an atom.
    • The net charge of an atom is determined by the electrons.
