Atomic Structure Test Review
Test i
s Wed, Oct 12th
. Study!!! You will NOT be able to use your review guide during the test. The review guide is to
help you know what you already understand and what you need to study more on.
Match the vocabulary word with the correct definition.
1. Proton a. Particles with no charge
found in the nucleus of
most atoms.
5. Atom e. Total number of protons
and neutrons in the
nucleus of an atom.
2. Neutron b. Center of atom. Contains
most of the atom’s mass.
6. Atomic
Number
f. The number of protons in
an atom. Also the way the
elements are numbered.
3. Electron c. Positively charged particle
in the nucleus of the atom.
Determines the element.
7. Atomic
Mass
g. The smallest part of an
element. The building
block of all things.
4. Nucleus d. Negative particles that are
found in the space around
the nucleus.
8. Electron
Cloud
h. The space outside the
nucleus where negatively
charged particles are
found.
9. Label the information below.
13. Finding the number of protons that an element has is easy, you just…
14. Finding the number of electrons that an element has is easy, you just…
15. Finding the number of neutrons that an element has is easy, you just…
16. Remember the nucleus is like a gym. The atomic __________ tells you everyone that is in the
gym. Only _____________ and ______________ can be in the gym. Boron has an atomic mass
of ___________. That’s like saying ____ people are in the gym. You already know 5 of those
people are girls ( 5 are ____________ ), therefore the rest are boys (or ______ neutrons.)
10. The atomic number tells me the
number of _______________________.
11. The atomic number also tells me the
number of _______________________.
12. Atomic mass tells me the TOTAL
number of ___________ AND _________.

  5. Remember the nucleus is like a gym. The atomic __________ tells you everyone that is in the

gym. Only _____________ and ______________ can be in the gym. Boron has an atomic mass of ___________. That’s like saying ____ people are in the gym. You already know 5 of those people are girls ( 5 are ____________ ), therefore the rest are boys (or ______ neutrons.)

  1. The atomic number tells me the number of _______________________.
  2. The atomic number also tells me the number of _______________________.
  3. Atomic mass tells me the TOTAL number of ___________ AND _________.
  1. Draw 5 protons in the nucleus of the atom. Label them with their charge.
  2. Draw 6 neutrons in the nucleus of the atom.
  3. Draw 2 electrons on the first energy level and label them with their charge.
  4. Draw 3 electrons on the second energy level and label them with their charge.
  5. What element is represented in the diagram? ______________
  6. That was easy! Now you try it. Complete the table for the element Beryllium. Then draw a model of one atom of Beryllium. Remember only two electrons can go on the first energy level.

Beryllium Atomic Number Atomic Mass

of Protons

of Electrons

of Neutrons

  1. You are going to compare the mass of the subatomic particles. Use the signs (=, <, >) to fill in the blanks so that each correctly relate to each other. Mass of a neutron ________ Mass of an electron Mass of an electron ________ Mass of a proton Mass of a neutron ________ Mass of a proton
  2. Be sure to review your notes from “The History of Atomic Theory”. You will be responsible for the scientists and their contributions to the structure and understanding of the atom.
  3. Label: nuclues, energy level, proton, neutron, and electron.
  4. When determining an element’s identity, what is the MOST important subatomic particle to examine? _______________________
  5. What is most of the volume of an atom occupied by? ___________________________________

Draw a model of Beryllium here.
