200

Describe the typical properties of a metalloid and give an example.

- exist as a brittle solid with a metallic luster

- are fairly conductive, increasingly so as the temperature rises

- reactivity varies 

200

- Any element in Group 18

300

How many neutrons does the element Tungsten (W) have?

110

400

The measure of an elements ability to attract and hold electrons is called...?

400

The elements on the stair-step of the Periodic Table are...

Metalloids

400

Using the periodic table, would you expect oxygen or selenium to act more like a non-metal?

Oxygen is farther from the stair-step so it should have a stronger non-metal character.
