5. HOW do you think ideas like the periodic table get widely known and accepted in the scientific
community? Do you believe it is easier or hard to happen now?

The periodic table is organized in such a way that they provide a great deal of information about elements and how they are related to each other.

Explanation:

The periodic table is used for better understanding of patterns and relationships between elements. With the elements arranged in the periodic table allow us to make synthetic elements.

This periodic table helped scientist to discover the elements that are needed for humans to survive. For example plants and animals need elements to grow and chlorine helps animals to digest food and in humans iron helps to carry oxygen around body and chlorine that convert the sun energy to food.

It provides information about elements and how they are related to each other in easy method. They are used to predict the properties of elements.

Thus, the Changes in periodic table is from the creation of new chemical elements and it helps the society in various applications that are used in mining, engineering and other occupations.

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.
