______________ describes the way a substance reflects light, or SHINES.
-
Magnetism
-
Brittleness
-
Luster
-
Ductility
Correct Answer
A. LusterExplanation
Luster refers to the way a substance reflects light or shines. It is a property that describes the appearance of a material, specifically how it interacts with light. Substances with high luster appear shiny and reflective, while substances with low luster appear dull. This term is commonly used in the context of describing the appearance of minerals or metals.Rate this question:

______________ describes how well the substance can be hammered into sheets.
-
Malleability
-
Conductivity
-
Ductility
-
Luster
Correct Answer
A. MalleabilityExplanation
Malleability is the property that describes how well a substance can be hammered or rolled into thin sheets without breaking or shattering. It is a measure of a material's ability to undergo plastic deformation under compressive stress. Malleability is an important characteristic for metals, as it allows them to be easily shaped and formed into various structures and objects.Rate this question:

What is the symbol of Iron?
-
Fe
-
Ke
-
Ef
-
Ee
Correct Answer
A. FeExplanation
Iron is symbolized by the chemical symbol "Fe." This symbol is derived from the Latin word "ferrum," which means iron. The use of symbols in chemistry allows for a concise and universal representation of elements. In this case, "Fe" is the recognized symbol for Iron in the periodic table and is widely used in scientific and chemical contexts.Rate this question:

Which of these is a nonmetal?
-
Iron
-
Copper
-
Coal
-
None
Correct Answer
A. CoalExplanation
Coal is a nonmetal because it is an organic sedimentary rock composed primarily of carbon, along with small amounts of other elements such as hydrogen, sulfur, oxygen, and nitrogen. Nonmetals are elements or compounds that lack metallic properties, such as being lustrous, malleable, and good conductors of heat and electricity. Coal does not possess these characteristics, making it a nonmetal, and coal is mainly composed of carbon. Iron and copper, on the other hand, are metals.Rate this question:

Ii
-
In
-

Iron atomic number is
-
22
-
24
-
26
-
80
Correct Answer
A. 26Explanation
The correct answer is 26 because the atomic number of an element represents the number of protons in the nucleus of its atom. Iron, being a transition metal, has an atomic number of 26, which means it has 26 protons in its nucleus.Rate this question:

If a substance breaks easily, it is said to be ________________.
-
Magnetic
-
Conductive
-
Brittle
-
Ductile
Correct Answer
A. BrittleExplanation
Brittle refers to the property of a substance to break easily without significant deformation or plasticity. It is the opposite of ductile, which refers to the ability of a substance to be stretched or drawn into a wire. Magnetic and conductive are unrelated properties that do not describe the tendency of a substance to break easily.Rate this question:

Metals are usually silver-grey in color.
-
True
-
False
Correct Answer
A. TrueExplanation
Most metals are indeed silver-grey in color due to the way their electrons absorb and re-emit photons, which results in the characteristic metallic sheen. However, there are exceptions with distinct colors, such as copper (reddish) and gold (yellowish).Rate this question:

Nonmetals are usually GOOD conductors of heat and electricity.
-
True
-
False
Correct Answer
A. FalseExplanation
Nonmetals are usually poor conductors of heat and electricity. Nonmetals are usually poor conductors of heat and electricity. Nonmetals have electrons that are highly attracted to the nuclei in nonmetallic substances, whereas metals have free-flowing electrons, allowing metals to conduct heat and electricity easily. Therefore, the statement that nonmetals are usually good conductors of heat and electricity is false.Rate this question:
-
- 11.
Nonmetals are not attracted to magnets.
-
True
-
False
Correct Answer
A. TrueExplanation
Nonmetals, such as carbon, oxygen, and nitrogen, do not possess magnetic properties. This is because their electron configuration does not allow for the alignment of magnetic moments within their atoms. Therefore, nonmetals are not attracted to magnets. Furthermore, not all metals are attracted to magnets.Rate this question:

Metals are soft and can bend or break easily.
-
True
-
False
Correct Answer
A. FalseExplanation
Metals are not soft and do not bend or break easily. In fact, metals are known for their strength and durability. They have high tensile strength and are often used in construction and manufacturing industries due to their ability to withstand heavy loads and resist deformation. Therefore, the statement that metals are soft and can bend or break easily is false.Rate this question:

Metals usually have high melting points.
-
True
-
False
Correct Answer
A. TrueExplanation
Metals have high melting points since they exist as crystalline solids. These crystalline solids are held together by metallic bonds wherein the free-flowing electrons are attracted to the positive metallic nuclei.Rate this question:
-
- 14.
Metals can be drawn into a wire.
-
True
-
False
Correct Answer
A. TrueExplanation
Metals can be drawn into a wire because they have high ductility, which means they can be easily stretched and shaped without breaking. This property is due to the metallic bonding, where metal atoms are arranged in a regular pattern and have loosely held electrons that can move freely. When a metal is subjected to a pulling force, the atoms can slide past each other, allowing the metal to be drawn into a wire. This property is essential in various applications, such as electrical wiring and jewelry making.Rate this question:

Ti stands for
-
Titanium
-
Sodium
-
Carbon
-
None of these
Correct Answer
A. TitaniumExplanation
Ti is the chemical symbol for Titanium. It is a chemical element with the symbol Ti and atomic number 22. Titanium is a strong, lightweight, and corrosion-resistant metal widely used in various industries such as aerospace, automotive, and medical. Therefore, Ti stands for Titanium.Rate this question:
