he called them molecules
Magnetism is created by the synchronized spins of atoms with unbalanced electron clouds. The lowest energy states for these unbalanced atoms is to align themselves with nearby atoms and spin in unison, creating the magnetic field we are familiar with. Most atoms have balanced electrons, or have electron configurations which do not have low energy states when aligned, thus no inclination to spin together in large groups, and no magnetic field.
Meatals: 88 Semimeatals: 6 Nonmeatals: 18 Add: Groups 1 and 18 contain 7 elements. Groups 2, 13-16 contain 6 elements. Groups 3-12 contain 4 elements. Some periodic tables do not include all of the elements 113-118 as only a few atoms of each have been observed in the laboratory.

The name apparently comes from "dimer" and "-yl" as in 'alkyl' or 'aryl,' common classes of organic radical functional groups. According to specification, 'dimeryl' is a hydrocarbon with 36 carbon atoms and two radicals. In dimeryl diisocyanate (DDI), isocyanate groups are attached to both functional points of the dimeryl biradical. There is apparently no such thing as "merylic acid".

Robert Boyle refounded the theory of atoms in his book The Sceptical Chymist (yes, there are some spelling mistakes in his original title).
because it is to small to be studied
symmetric carbon atoms are those atoms in which the carbon atoms valency is satisfied by same atoms r groups functional groups

No. Atoms are divided into groups according to their proprieties and electron configurations.

Robert Boyle's book on acids and alkalis, "The Sceptical Chymist," was important because it questioned traditional alchemical theories and laid the foundation for modern chemistry. Boyle proposed the idea that matter was made up of atoms and introduced the concept of chemical elements as distinct substances. His work helped to shift the focus of chemistry from mystical beliefs to empirical observations and experimentation.
Functional groups are the atoms or groups of atoms which largely defines the chemical properties of any organic compound. Eg: ch3-oh are alcohols
