Respuesta :
Element Z can be classified as a metal and will be found to the left of the zigzag line of the periodic table.
Hence, option 3 is correct answer.
What is Metal and Non metal ?
Metals are solid at room temperature. Metals are malleable. Metals loses electrons easily. Metal are less electronegative. Non metals are non malleable. Non metals cannot loses electron. Non metals are more electronegative.
What is Zig-Zag line in periodic table ?
The Zig-Zag line called the amphoteric line, the semimetal line, the metal non metal line, the stair case and the metalloid line on the periodic table separates the metals from the non metals.
Thus from the above conclusion we can say that Element Z can be classified as a metal and will be found to the left of the zigzag line of the periodic table.
Hence, option 3 is correct answer.

Question: Element Z has the following properties:
a. silvery-white solid at room temperature
b. malleable
c. used as a catalyst
d. conducts electricity
Element Z can be classified as a _________ and will be found ________ the zigzag line of the periodic table.
(1) non-metal; along side of
(2) metal; along side of
(3) metal; to the left of
(4) metalloid, along side of
(5) non-metal; to the right of
Option 3 is correct
Element Z can be classified as a metal and will be found to the left of the zigzag line of the periodic table.
As the element Z conducts electricity, so it is a metal.
Metals can be hammered, crushed, or rolled into thin sheets without breaking due to a feature known as malleability.
As the given element Z is malleable, so it is a metal.
Most transition metals are also used as catalyst because they can activate other compounds by adsorbing them to their surface. As the element Z is used as catalyst, so it is metal.
Some other physical properties of metals are :
1) They are also good conductor of heat.
2) Highly ductile
3) They are lustrous
4) They are sonorous
Metals are present on the left side of the zig-zag line (the line that separates metals and non metals) whereas non-metals are present on the right side of this line.
As the Element Z is metal on the basis of the given properties left side of the zig-zag line, so it will be found to the left of the zigzag line of the periodic table.
Hence option (3) is correct
