NYSTCE CST Chemistry - Exam Topics Sample Questions

There are how many elements on the periodic table?

Correct Answer:
118


the correct answer to the question of how many elements are on the periodic table is 118. as of the latest updates, the periodic table comprises 118 distinct elements, each with unique properties and atomic structures. the periodic table is a tabular arrangement of these elements, organized on the basis of their atomic numbers, electron configurations, and recurring chemical properties.

out of the 118 elements, 92 occur naturally on earth. these naturally occurring elements range from hydrogen, which has the atomic number 1, to uranium, which has the atomic number 92. elements beyond uranium, from neptunium (atomic number 93) to oganesson (atomic number 118), are synthetic and have been created artificially in laboratories through nuclear reactions.

the creation of synthetic elements is a complex process that typically involves bombarding lighter elements with ions or neutrons to add protons to their nuclei. this process often results in very unstable elements that decay rapidly into lighter elements. their instability and rapid decay rates mean that these elements exist only momentarily before transforming into other elements.

the most recent additions to the periodic table include elements 113 (nihonium, nh), 115 (moscovium, mc), 117 (tennessine, ts), and 118 (oganesson, og), which were officially named and added to the seventh row of the periodic table at the end of 2016. these elements were synthesized in joint collaborations by scientists in russia, the united states, and japan, marking significant achievements in the fields of chemistry and physics.

understanding the properties and interactions of all 118 elements helps scientists and researchers to develop new materials, medicines, and technologies, contributing to advancements in various fields including healthcare, engineering, and environmental science. the periodic table not only serves as a fundamental tool in science education but also as a framework for scientific research and development across multiple disciplines.
