(10 cards)
What is Elemental Forms
An element can exist in two or more different forms, known as allotropes
For carbon, these forms include diamond, graphite, and coal
What are allotropes ?
Allotropes are different forms of the same element that have identical chemical properties but different physical properties
For example, carbon can exist as diamond, which is hard and transparent, and graphite, which is soft and opaque
physical properties of carbon
Carbon allotropes exist in solid form, exhibiting different physical properties such as color and hardness
Diamond is shiny and transparent, while graphite is black and opaque
what are the chemical properties of carbon
All forms of carbon react with oxygen to produce carbon dioxide, indicating they share identical chemical properties
Define diamond
Structure: Carbon atoms are linked in a tetrahedral arrangement, forming a strong bond
Properties: Hard, transparent, and a poor conductor of electricity due to the absence of free electrons
High melting point of 3700 °C
define graphite
Structure: Composed of layers of carbon atoms arranged in hexagonal rings, allowing layers to slide over each other, making it soft and slippery
Properties: Good conductor of electricity due to free electrons, used in lubricants and batteries
where is diamond used ?
Diamond: Used in cutting tools and drill bits due to its hardness
where is graphite used ?
Graphite: Utilized in pencils, lubricants, and as a conductor in batteries
define coaLL
Coal: A form of carbon used as a fuel source, known for its smokeless burning properties when processed into coke
WHAT IS SOOT
Soot: Produced from incomplete combustion of carbon, used in black paints and inks
