1. This is the weighted average of all the isotopes of an element.
2. This is the number of protons.
3. This is a substance that cannot be broken down further by chemical means.
4. This is an element with a full valence shell, very unreactive.
5. This is a type of element that has many valence electrons, not a conductor.
6. This is a group of elements with few valence electrons that conducts heat and
electricity.
7. This is the highly reactive family of elements with 7 valence electrons.
8. A horizontal row of elements in the periodic table.
9. An arrangement of elements into rows and columns according to similarities in
their properties.
10. One of a class of elements having properties intermediate to metals and
nonmetals.

11. These are the highly reactive elements located in Group 1 of the periodic table.
These elements have one electron in their outer energy level which makes them
highly reactive with water and halogens.
Average Atomic
12. These are the reactive elements located in Group 2 of the periodic table. These
elements have two electrons in their outer energy level which makes them reactive
with water and halogens.

13. These are the Group 3 or d-block elements. These dense metals with high
boiling points can have different oxidation states and all are solid at room
temperature with the exception of mercury.
14. This is a property of solid metals. Capable of being shaped or formed, by
hammering or pressure.
