periodic table matter vocabulary assignment
using the word bank below, fill in the blanks with the correct word. use your vocabulary definitions and notes to help you.

1. the ______________________ is the mass of the protons, electrons and neutrons added together.
2. when light reflects from the surface of rocks, crystals or minerals, this is called ______________.
3. ______________________ is when a substance combines with oxygen and causes iron to rust, discoloration in metals and rotting of food.
4. rare gases that are very stable and low reactivity are called ______________________.
5. jewelry and silverware have ______________________ because they can be molded into different shapes and styles.
6. a quick reference of all the elements which includes atomic mass, atomic number and chemical symbols is the ______________________.
7. the number of protons in the nucleus of an element, listed on the periodic table is the elements ______________________.
8. rubber, glass, and wood are examples of ______________. these are poor conductors of electricity.
9. when the metals break down due to weather, atoms are oxidized causing ______________.
10. very reactive elements in group 1 of the periodic table are ______________________.
11. metals, water, and the human body all display ______________________ because electricity flows through them easily.

Explanation:

1. Atomic mass is the sum of protons, electrons and neutrons' mass.
2. Luster is the reflection of light from surfaces of rocks, etc.
3. Oxidation occurs when a substance combines with oxygen causing rust, etc.
4. Noble gases are rare, stable and low - reactivity gases.
5. Ductility allows materials like jewelry and silverware to be molded.
6. The periodic table is a quick reference for elements with atomic mass, number and symbols.
7. Atomic number is the number of protons in an element's nucleus.
8. Insulators, like rubber, glass and wood, are poor conductors of electricity.
9. Corrosion happens when metals break down due to weather and oxidation.
10. Alkali metals are very reactive elements in Group 1 of the periodic table.
11. Conductivity is shown by metals, water and the human body as electricity flows through them easily.
