Titanium is brittle and insulates heat.
The class is recording the properties of several samples of matter. Their observations are in the table below.
Based on the observations, which sample is most likely a metalloid?
Sample W
Sample X
Sample Y
Sample Z
Students recorded properties of elements found on two sections of the Periodic Table shown below.
Which chart below most likely describes the elements in each section?
Which element is most likely a metal?
1
2
3
4
What other properties would you expect the metal on this table to have?
Malleable
Ductile
Gas at room temperature
Magnetic
Students were conducting experiments on several samples of matter. They drew a table to recordtheir observations. The students need to complete the table with a title.
What title should the students use for their table?
Physical Properties of Nonmetals
Physical Properties of Metals
Physical Properties of Metals and Nonmetals
Physical Properties of Metalloids
A student is trying to classify an unidentified, solid gray material as a metal, nonmetal, or metalloid.
The element has a shiny luster but is not malleable.
Which element is the student likely classifying?
Neon (Ne)
Silicon (Si)
Tungsten (W)
Iron (Fe)
Copper (Cu), Phosphorus (P), and Iodine (I) are elements found on the periodic table as shown below.
Tests involving these three elements would show that --
Iodine (I) is malleable and conducts electricity.
Copper (Cu) is malleable and conducts electricity.
Phosphorus (P) is malleable and Copper (Cu) conducts electricity.
all three elements are malleable but do not conduct electricity.
Students were observing certain elements on the Periodic Table. The elements are shown below.
Which statements correctly compares metals and nonmetals?
Chromium (Cr) is dull and brittle.
Sulfur (S) is shiny and malleable.
Cobalt (Co) is a good insulator of electricity.
Carbon (C) tends to be a good conductor of electricity.
Platinum (Pt) cannot be stretched into thin wires.
Chlorine (Cl) can be stretched into think wires.
Magnesium (Mg) tends to be a good conductor of thermal energy.
Argon (Ar) tends to be a good insulator of thermal energy.
Using your periodic table, pick three elements that are dull, brittle, and good insulators of electricity.
Iodine
Boron
Xenon
Hydrogen
