C4.8A Identify the location, relative mass, and charge for electrons, protons, and neutrons.
C4.8B Describe the atom as mostly empty space with an extremely small, dense nucleus consisting of the protons and neutrons and
an electron cloud surrounding the nucleus.
C4.8C Recognize that protons repel each other and that a strong force needs to be present to keep the nucleus intact.
C4.8i Describe the fact that the electron location cannot be exactly determined at any given time.
C4.10B Recognize that an element always contains the same number of protons.
C4.10e Write the symbol for an isotope, XZA, where Z is the atomic number, A is the mass number, and X is the symbol for
the element.
Students Must:
 Describe the atom as mostly empty space with an extremely small, dense nucleus
consisting of the protons and neutrons and an electron cloud surrounding the nucleus.
 Recognize that an element always contains the same number of protons.
 Describe the location, mass, and charge of protons, electrons, and neutrons
 Calculate the number of protons, electrons, and neutrons in neutral atoms
 Define and use atomic number, mass number, isotope, valence electrons, and ion
 Identify atoms based on descriptive information
 Draw pictures of atoms
 Describe the fact that the electron location cannot be exactly determined at any given
time.
 Use each of the two labeling methods for atoms shown in class
