What else can I help you with?
What are the theories of chemistry?
- atomic theory- law of mass conservation- periodicity law- law of multiple proportionsand many others
What does a compound have to contain to be organic?
Organic Chemistry is defined as 'The Chemistry of Compounds of Carbon'.
Who first gave the concept of periodicity?
The concept of periodicity was first introduced by Dmitri Mendeleev when he created the periodic table in 1869, which arranged the elements based on their atomic mass and properties. Mendeleev's table allowed for the prediction of the properties of undiscovered elements and is considered a landmark achievement in the field of chemistry.
What are amorphous solids made of?
All amorphous solids are composed of particles with no crystalline structure that has any sort of periodicity, the most common of which, perhaps, is glass. This means that the particles have no ordered arrangement. This is opposed to crystalline solids which do have a well defined periodicity and have long range order.
Why Mendeleev was able to observe periodicity?
mendeleev arranged elements according to atomic mass. He was able to observe periodicity when arranged in this pattern.
Periodicity is best defined as?
The repitation of physical and chemical properties of elements periodically is called periodicity
What are the theories of chemistry?

What does a compound have to contain to be organic?
Organic Chemistry is defined as 'The Chemistry of Compounds of Carbon'.
How do the atomic numbers of the elements with in each of group 1 2 and 13-18 of the periodic table vary?
Mendeleev's Periodic Table -- the reason for periodicity -- is explained by the arrangement of the electrons around the nucleus. *Read your chemistry book* :D

What might you find in a Chemistry dictionary?
In a chemistry dictionary one will find a list terminologies and words related to chemistry. Each chemical and element will be defined with its uses explained.
What does lack of periodicity in medical terms mean?
Lack of periodicity means there's no pattern of repeat or recurrence.
How is organic defined?
Organic is any chemical containing carbon when pertaining to chemistry.
How is the word 'chemistry' defined?
Chemistry is the natural science that studies the structure and behavior of matter at the microscopic scales of molecules, atoms, and subatomic particles.
What is the definition of pure water in chemistry?
Pure water in chemistry is defined as water that contains only H2O molecules and no other substances or impurities.
Why are you taking chemistry?
"Chemistry" is a hard word to define. Some chemistry textbook covers show pictures of bubbling flasks, suggesting that chemistry can be defined as "the study of how we can make things behave if we mess with it in the laboratory." Other chemistry books have pictures of huge molecules on the cover, suggesting that chemistry is defined as "the study of how we can cram atoms together to make big complicated structures." I've even seen a textbook cover that featured a multicolored squiggle. I have no idea what that says about the study of chemistry. It seems to me that if we put these two definitions of chemistry together, we get a reasonable idea of what the subject actually entails. Chemistry can be defined as using our knowledge of how matter is put together and how it interacts with other matter to solve confusing problems.
Who is the best teacher of chemistry?
Dr. Duncan is the best teacher of chemistry and her lil dog plumbum!!!!
