Niobium is a chemical element with symbol Nb and atomic number 41, which is often found in the pyrochlore mineral, the main commercial source for niobium. It is a lustrous, grey, ductile, paramagnetic metal in group 5 of the Periodic Table, although it has an atypical configuration in its outermost electron shells compared to the rest of the members.
The metal takes on a bluish tinge when exposed to air at room temperature for extended periods. Despite presenting a high melting point in elemental form (2468 °C), it has a low density in comparison to other refractory metals, it is corrosion-resistant, exhibits superconductivity properties and forms dielectric oxide layers.
Electron Configuration: 41Nb [2, 8, 18, 12, 1]
Niobium is a shiny, gray metal with a high melting point and low density. It is corrosion-resistant in many environments due to the formation of a protective oxide layer. Niobium exhibits superconducting properties at low temperatures and is used in various high-tech applications.

What happens to the chemical and physical properties of a substance formed in a chemical reaction?
The chemical properties of a substance change during a chemical reaction, meaning the substance undergoes a chemical change and forms new substances with different properties. The physical properties may also change, such as color, texture, or state of matter.
Which type of properties is easier to recognize physical or chemical?
Physical properties are generally easier to recognize compared to chemical properties because physical properties can be observed or measured without changing the substance's chemical composition. Examples of physical properties include color, size, shape, density, and melting point.
Are properties such odor color density and solubility physical or chemical properties?
Odor, color, density, and solubility are physical properties of a substance. These properties can be observed or measured without changing the chemical composition of the substance.
Are boiling points and freezing points examples of chemical properties?
No, boiling points and freezing points are examples of physical properties, not chemical properties. Chemical properties describe how a substance interacts with other substances to form new substances, while physical properties describe characteristics that can be observed without changing the chemical composition of the substance.
Is the luster of silver jewerly a physical property?
Yes, the luster of silver jewelry is a physical property. Luster refers to the shininess or reflective quality of a material's surface, which is a characteristic that can be observed without changing the chemical composition of the silver.
Does chemical and physical properties are probably the same?
No. Chemical and physical properties are different.
When do the physical and chemical properties change?
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.
Difference between chemical and physical change?
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
Does copper have chemical or physical?
Copper has both chemical and physical properties. Chemical properties refer to how copper reacts with other substances, while physical properties refer to characteristics like its color, density, and conductivity.
Is sour milk a chemical properties or a physical properties?
Chemical property

Is a property of matter chemical or physical?
Matter has chemical properties (ex.: chemical reactivity) or physical properties (ex.: thermal conductivity).
Are fertilizers physical or chemical properties?
chemical
What are physical and chemical?
physical changes do not change the chemical properties of a substance
What are properties that change?
the properties that change are physical and chemical properties!!! :)
Which type of properties is easier to recognize physical or chemical?
Physical properties are generally easier to recognize compared to chemical properties because physical properties can be observed or measured without changing the substance's chemical composition. Examples of physical properties include color, size, shape, density, and melting point.
Elements in a column are called . These elements have similar chemical and physical properties.?
These elements have similar chemical and physical properties.
