Answer:
B. By atomic number.
Explanation:
The atom is the most basic unit of matter with properties of a chemical element. The atom is the fundamental component of all matter. All atoms are made up of a central nucleus in which there are positively charged particles, the protons, around which other negatively charged particles, the electrons, move. The nucleus of the atom also has neutrons, which have a neutral charge.
The atomic number, which is represented by the letter Z, indicates the number of protons that are present in the nucleus of an atom. Determine the identity of an atom and its properties.
The atomic number is used to classify the elements within the periodic table of the elements.
Answer:
there are two types of nomenclature used in organic system. the most widely used and universally accepted system of nomenclature is the IUPAC system of nomenclature. some compounds are referred to by their common name that existed before the IUPAC system or is more widely known than the IUPAC names.
Explanation:
IUPAC ( international union of pure and applied chemistry) system of nomenclature is used to name compounds in organic system. there are some principles to be followed while using this nomenclature. some of them are:-
1) identification of parent chain is the first step. the longest hydrocarbon chain is the parent chain.
2) identification of all the substituent groups of the parent chain is also required.
3) hydrocarbon cyclic ring has a fixed prefix and that is cyclo.
Answer:
scientists often communicate their research results in three general ways:
1) One is to publish their results in peer-reviewed journals that can be ready by other scientists.
2) Two is to present their results at national and international conferences where other scientists can listen to presentations
