- 3. A substance that does not exhibit such characteristic properties of metals as hardness, mechanical adaptability, or the ability to conduct electricity.
- 6. Any of the elements beryllium, magnesium, calcium, strontium, barium, and radium, occupying Group 2 of the periodic table. They are reactive, electropositive, divalent metals, and form basic oxides that react with water to form comparatively insoluble hydroxides.
- 8. Any of the elements lithium, sodium, potassium, rubidium, cesium, and francium, occupying Group 1 of the periodic table.
- 11. All elements in the s and p blocks of the periodic table. The most abundant elements in the periodic table.
Down
- 1. Have full valence orbitals; Any of the gaseous elements helium, neon, argon, krypton, xenon, and radon, occupying Group 0 (18) of the periodic table.
- 2. An inner transition metal (ITM) is one of a group of chemical elements on the periodic table. They are normally shown in two rows below all the other elements. They include elements 57-71 (lanthanides) and 89-103 (actinides).
- 4. The elements that feature atoms that have an incompleted sub-shell.
- 5. Have 7 electrons in their outer shells, giving them an oxidation number of -1.
- 7. Any chemical element that is an effective conductor of electricity and heat can be defined as a metal.
- 9. An element whose properties are intermediate between those of metals and solid nonmetals.
- 10. The physical and chemical properties of the elements recur in a systematic and predictable way when the elements are arranged in order of increasing atomic number.
