STANDARDS:
I can describe the relative charges, masses, and locations of the protons, neutrons, and electrons in an atom of an element.
When given the number and arrangement of electrons in the outermost shell of an atom, I can predict the chemical properties of the element.
When given the number of protons, I can identify the element using a
Periodic Table.
When given the atomic number and atomic mass number of an isotope, I can draw and label a model of the isotope’s atomic structure (number of protons, neutrons, and electrons).
DRAW AND LABEL THE ABUNDANT ISOTOPE OF YOUR ATOM:
1.
You will be given a paper with the atomic number and mass number of an atom. Paste your paper to your drawing.
2.
Create a drawing of an atom using colored dots to represent particles.
3.
Use information from the periodic table to find out the name of your element.
4.
Use 3 colors of markers to show different particles of the atom (protons, neutrons, electrons). Yes, your atom will NOT be to scale!
5.
Include a key that indicates which colors represent which particles, the name of the element, atomic symbol, # of valence electrons, atomic number, number of protons, number of neutrons, total number of electrons, and mass number.
6.
Make a distinct nucleus of protons and neutrons.
7.
Place electrons in three levels. The inner shell should have 2 electrons, the outer shell should contain the correct number of valence electrons (remember the secret from the periodic table!) and the rest belong in the middle, evenly spaced ( remember how many electrons fill each shell).
8.
Represent in some way the “behavior” of the electrons.
9.
Include charge symbols (+, -, 0) on all particles
10.
Make sure your atom is neutral. In other words, your atom should have the same number of + charges as it has – charges.
DRAW AND LABEL THE ADDITIONAL ISOTOPE OF YOUR ATOM:
1.
Repeat the steps above, except use the mass number of the additional isotope.
DRAW AND LABEL AN ION:
1.
Repeat the steps above, except in step 10, instead of being neutral, your atom will have a positive or negative charge, as indicated. Make sure you have the correct number of electrons to give the atom the correct charge.
