Across
- 3. Earth This is the second most reactive group of elements on the periodic table, these are found in group 2.
- 4. Gases This group of elements makes up the last row in the periodic table. Each element in this group has a full valence shell of electrons.
- 6. A chemical property that describes the tendency of an atom to attract electrons towards itself.
- 7. This group of nonmetals has elements with 7 valence electrons in their outer shell.
- 9. Energy The amount of energy required to remove the most loosely bound electron, the valence electron, of an isolated gaseous atom to form a cation
- 11. This type of bond involves the sharing of electrons between two or more atoms.
- 12. This is the most reactive group of metals, found in group 1 on the periodic table.
- 13. This type of bond involves the complete transfer of electrons between two or more elements.
Down
- 1. This group of metals is made up of elements between group 2 and 12 on the periodic table. They have valence electrons in multiple shells.
- 2. This small category of elements shows characteristics of both metals and nonmetals. There are only 7 of them.
- 5. This category of elements makes up the majority of the periodic table. They are identifiable by their hardness, ability to conduct electricity, and is a good thermal conductor.
- 8. This category of elements makes up the right side of the table, including group 18. They generally exist as gases and solids.
- 10. Radius A measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding cloud of electrons
