Allotropes are different structural forms of the same element and can exhibit quite different physical properties and chemical behaviours.
Why allotropes have different physical properties but same chemical properties?
Allotropes exhibit multiple structural shapes in the same phase due to changes in atom bonding. The atoms involved will be the same, but the bonding arrangement will be different. As a result, the chemical reaction differs.
Which properties of allotropes are similar?
Allotropes of carbon have a different physical form but chemically they are similar, e.g., diamond and graphite are allotropes of carbon which are chemically carbon compounds but physically diamond is the hardest material known while graphite is soft material.
Why do allotropes of carbon have different properties?
In all three allotropes, the carbon atoms are joined by strong covalent bonds , but in such different arrangements that the properties of the allotropes are very different.
What are the characteristics of allotropes?
Properties of Allotropes: Allotropes have different crystalline shapes due to different arrangements of particles. Allotropes have different physical properties. Allotropes have the same chemical properties due to the same chemical composition.
Which of the following will have same chemical properties?
Isotopes have same electronic configuration as they have same atomic number. Thus they have similar chemical properties. Hence the correct answer is option A. Isotopes.
Do Isotopes have the same chemical properties?
Many isotopes occur naturally. Usually one or two isotopes of an element are the most stable and common. Different isotopes of an element generally have the same physical and chemical properties because they have the same numbers of protons and electrons.
Do diamond and graphite have the same chemical properties?
Diamond and graphite show different physical properties although they are made up of carbon and show the same chemical properties.
Do isomers have same physical properties?
Compounds having the same chemical formula but different physical and chemical properties are called isomers. The phenomenon is known as isomerism.
How are two allotropes different?
Allotropes may display very different chemical and physical properties. For example, graphite and diamond are both allotropes of carbon that occur in the solid state. Graphite is soft, while diamond is extremely hard. Allotropes of phosphorus display different colors, such as red, yellow, and white.
What is the difference between allotropes and allotropy?
Allotropy is a property that is exhibited by elements that exist in multiple forms and these elements have different atomic structures. An allotrope is a form of the element that has a different structure from the other form of the same element. They are different physical forms of a particular element.
What is an allotrope explain the difference in properties of different allotropes of carbon?
When an element possess two or more different forms in the same state, they are called allotropes and the phenomenon is known as allotropy. Diamond and graphite are the two allotropes of carbon.
Is Coke an allotrope of carbon?
Coke and coal are amorphous allotropes of carbon.
What are the physical properties of a diamond?
- Hardness.
- Low coefficient of friction.
- High thermal conductivity.
- High electrical resistivity.
- Low thermal expansion coefficient.
- High strength.
- Broad optical transparency from ultra violet to infra red.
- Resistant to chemical corrosion.
Which element has the property of allotropy?
Elements exhibiting allotropy include tin, carbon, sulfur, phosphorus, and oxygen.
Do all elements have allotropes?
The elements carbon, oxygen, sulfur, tin and phosphorus all have allotropic forms. Carbon is considered to be monotropic, as graphite is more stable than diamond. Oxygen is also considered to be monotropic as molecular oxygen (O2 – in the air) is more stable that ozone (O3 – triatomic oxygen) under natural conditions.
What is an allotrope simple definition?
Definition of allotropy : the existence of a substance and especially an element in two or more different forms (as of crystals) usually in the same phase.
Which elements have similar physical properties?
The answer is b. Elements in the same group have the same number of valence electrons and so interact with other elements in a similar way. They display similar physical and chemical properties. For example, the halogens (F, Cl, Br, I) all react similarly.
How are the allotropes of carbon similar in their chemical properties?
The chemical elements that have a different number of protons but the same mass number are known as isobars. When a chemical element exists in two or more physical forms are known as allotropes. All allotropes have the same element.
What has the same physical properties but different chemical properties?
Different allotropic forms of an element have same physical properties but different chemical properties. Different allotropic forms of an element have same physical properties but different chemical properties.
Are physical properties of isotopes the same?
Isotopes of an element have different physical properties because they have different mass numbers. Chemical properties of different isotopes are almost similar. When it comes to physical properties of isotopes including mass, melting or boiling point, density, and freezing point, they are all different.
Why do isotopes have same physical properties?
All the Isotopes of an element have identical chemical properties because they have the same number of electrons as an atom of that element but they have different numbers of neutrons. The different number of neutrons affects the mass number.
Do isobars have same physical properties?
Isobar are elements that differ in chemical properties but have the same physical property. So, we can say that isobars are those elements that have a different atomic number but the same mass number.
Why do diamond and graphite have different physical properties even though they?
Diamond and graphite are both allotropes of carbon. This means even though they are made up of the same element- carbon, the structure in which the carbon atoms are arranged is different which results in the difference in physical properties.
Which property is similar in diamond and graphite?
As both graphite and Diamond are allotropes of carbon, the atomic weight of either of them will be equal to the atomic weight of carbon.
