Interpretation:
The given elements are to be classified as metals, metalloids, and non-metals.
Concept introduction:
Metals are present on the left side of the periodic table. These are mainly solid at room temperature and are good conductors of electricity and heat.
Non-metals lie on the top right of the periodic table. Non-metals are either solids or gases at room temperature and are poor conductors of heat and electricity.
The elements which show the properties of both metals and non-metals are known as metalloids.
The periodic table shows the metals in blue color, non-metals in shale-yellow color, and metalloids in orange color.
Answer to Problem 1QP
Solution:
(a) Metal
(b) Metalloid
(c) Non-metal
(d) Non-metal
(e) Metal
(f) Metal
(g) Metalloid
(h) Metal
Explanation of Solution
a) Cs
Cs appears on the left end of the periodic table. This is usually solid at room temperature and is a good conductor of heat and electricity.
Hence, this element is a metal.
b) Ge
Ge shows the properties of both metals and non-metals. It exists as a semiconductor.
Hence, this element is a metalloid.
c) I
I appears on the extreme right of the periodic table. It exists as a solid at room temperature and is a poor conductor of heat and electricity.
Hence, this element is a non-metal.
d) Kr
Kr appears on the extreme right of the periodic table. It exists as a gas in the atmosphere and is a poor conductor of heat and electricity.
Hence, this element is a non-metal.
e) W
W appears on the left end of the periodic table. This is usually solid at room temperature and is a good conductor of heat and electricity. W has a tendency to lose electrons from its outermost shell.
Hence, this element is a metal.
f) Ga
Ga appears on the left end of the periodic table. This is usually solid at room temperature and is a good conductor of heat and electricity. Ga has a tendency to lose electrons from its outermost shell.
Hence, this element is a metal.
g) Te
Te shows the properties of both metals and non-metals. It exists as a semiconductor.
Hence, this element is a metalloid.
h) Bi
Bi appears on the left end of the periodic table. This is usually solid at room temperature and is good conductor of heat and electricity.
Hence, this element is a metal.
