How many chemical elements can you specify? One in five Americans cannot mention one.

Science

Time to refresh a science course? One in five Americans cannot determine elements in the periodic table.

Most of the Americans surveyed (59%) could not identify more than 10 of the 118 items that graced the periodic table. This may be the result of the question asked: Americans may know many names of goods (gold is one, and other household names such as silver, tin, tin, oxygen, helium, and calcium), but cannot be realized. actually they are elements.

This new study comes from a non-governmental organization Science Institute of History based in Philadelphia. This is managed by the YouGov consulting organization, which studies 1,263 adults online and weighs answers to represent the demographics of adults in the US.

Primary Periodic Table
Elements are the main building blocks of matter; Substances get points in the periodic table because they cannot be broken down into something simpler. This graph, which adorns research branches around the world, dates from 1869, when Russian chemist Dmitry Mendeleyev presented his new way to organize popular atomic mass elements (the number of protons and neutrons in atoms) and valence (maximum number of electrons). in the outer shell of atoms, which are available to bind other atoms).

The periodic table was last updated in 2016 when four new elements were introduced. For those who want to visit the next Science Institute research, their names are Nihonium, Moskito, Tantezin and Oganeson. These elements are super-heavy with protons 113, 115, 117 and 1118 at the core. This means they are very unstable. They do not occur naturally, and when they are created in the laboratory, they quickly disintegrate into other, more stable elements.

The study found that 57% of Americans believe in the importance of science, while 45% believe that it is important to balance scientific development. However, there are gaps in basic scientific knowledge. Seventeen percent of Americans are afraid to keep up with the times, and 24 percent demand better access to scientific information.

Rare earth
This study also leads to misunderstandings about rare earth elements. Twenty-six percent of respondents did not hear the term and 35 percent heard it, but they did not know what that meant.

Rare earth elements are 17 elements with atomic numbers 57 to 71 and 21 and 39. They are metals with similar properties and are important components of many modern technologies, from portable electronic devices to fuel cells to lasers. They have their names because they rarely meet in concentrated deposits, but they are actually very common in the world. Your names are Scandium, yttrium, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, disprosium, holmium, erbium, thulium, ytterbium and lutetium (about five times faster).

This study found that people are very interested in the technology that is possible with these elements. 54 percent said they could not live without the internet, and 41 percent said they could not live without their smartphones. About 1 in 3 says that clean energy technology and progress in the fight against climate change will be the most important technology in the future, while 20% for health technology and 18% communication technology with the greatest impact in the future. Everyone depends on rare earths.
