ARMOR MANUAL
WELCOME SCI OPERATIVE! Your armor is an essential defense against THE
HIVE's attacks, but we need to understand why it is malfunctioning after being blasted with a beam from THE HIVE's latest machine. As you move through this training manual, pay special attention to the composition of the armor material so we can determine how to better defend ourselves against THE HIVE.
To complete this training session log into your SCI OPS: GLOBAL DEFENSE account (https://play.plasma.games) and use the information given to you about the armor in the laboratory and in the accompanying videos.
OBJECTIVE 1: ESSENTIAL ARMOR VOCABULARY
ATOMIC STRUCTURE
NAME:
The most basic units of matter are called. An is made up of a central area called a (which is composed of and ) and surrounded by a cloud of tiny.
Match each vocabulary word with its definition.
1. Matter 2. Atom 3. Nucleus 4. Proton 5. Neutron 6. Electron 7. Atomic Number 8. Element 9. Isotope
A substance made up of one (and only one) type of atom. Subatomic particle that is located in the nucleus and has no charge. Smallest unit of matter. Small, dense, central region of the atom where protons and neutrons are located. Any substance that has mass and occupies a volume of space. Subatomic particle that is in the nucleus and has a positive charge. Atoms of the same element with differing numbers of neutrons. Subatomic particles that move quickly around the nucleus in orbits and have a negative charge. The number of protons in an atom's nucleus.

OBJECTIVE 2: UNDERSTANDING WHAT ARMOR IS MADE OF Make sure you have completed level 2, including upgrading your armor, in order to view the lab text. Remember to click on blue words to open a separate vocab box with more information Continue to USE THE TEXT IN THE LABORATORY to learn the information needed to complete the blanks below:
PROTONS HAVE A CHARGE. The number of protons is unique to each element and symbolized by the.
NEUTRONS HAVE CHARGE. Neutrons are similar in size to protons and keep like charged protons from repelling one another. The number of neutrons and protons in the nucleus are not always equal. Neutrons must be calculated using the atomic mass and atomic number.
ELECTRONS HAVE A CHARGE.
Electrons move quickly around the nucleus in the , represented here as rings. The electrons cloud is made up of. The mass of an electron is so small that it is considered negligible.

NEUTRONS
PROTONS
OBJECTIVE 3: UNDERSTANDING THE PERIODIC TABLE In order to figure out how many protons, neutrons, and electrons there are in an atom, we first need to know how to read the PERIODIC TABLE OF ELEMENTS. Each box on a Periodic Table will have a series of symbols and numbers shown. Some Periodic Tables will also add in additional specialized information for specific uses. However, no matter the Periodic Table, there are four main pieces of information that are included: The ATOMIC NUMBER, ATOMIC MASS, ELEMENT SYMBOL, and ELEMENT NAME. We can use this information to figure out the structure of an atom.

Protons, electrons, and neutrons are called SUBATOMIC PARTICLES and are too small to see with an optical microscope. Size at an atomic level is measured in nanoscale!
How do these subatomic particles compare in size, location, and mass?
