Detailed explanation-1: -Answer and Explanation: The substances that can be found on the periodic table are elements. The table is called “periodic table of elements” for a reason.
Detailed explanation-2: -Scientists use the periodic table to quickly refer to information about an element, like atomic mass and chemical symbol. The periodic table’s arrangement also allows scientists to discern trends in element properties, including electronegativity, ionization energy, and atomic radius.
Detailed explanation-3: -The letter “J” is the only one not found on the periodic table.
Detailed explanation-4: -Elements 1 through 92 (except for elements 43 and 61) occur naturally on Earth, although some are only present in extremely small quantities. The elements following uranium on the periodic table are only produced artificially, and are known as the transuranium or transuranic elements.
Detailed explanation-5: -To date, the highest atomic number element to be discovered or synthesized is oganesson (symbol Og), with atomic number 118. This is something of a “magic” number because it completes the seventh row of the periodic table of elements.
