We break down the anatomy of these structures to display this for students and we will explore the Bohr model of this structure. Students will learn how to predict the element formed based on the number of protons an atom has. We will look at how mass number affects the balance of the atom.

Define, neatly and clearly, the following atomic structure related terms. 1. Nucleus 2. Neutron 3. Proton 4. Electron 5. Nucleons 6. Atomic number 7. Mass number 8.
Fill in the blanks in the following worksheet. Please keep in mind that the isotope represented by each space may NOT be the most common isotope or the one closest in atomic mass to the value on the periodic table.
How many neutrons are in the nucleus of an atom that has an atomic mass of 36 and an atomic number of 25? Draw a Bohr model of an oxygen atom in the space below. Be sure to place the electrons in the correct orbitals and to fill out the key for the subatomic particles.
2. The number of protons in one atom of an element determines the atom’s _____, and the number of electrons determines the _____ of the element. 3. The atomic number tells you the number of _____ in one atom of an element. It also tells you the number of _____ in a neutral atom of that element.
