Students will begin to look closely at the periodic table. They will be introduced to the basic information given for the elements in most periodic tables: the name, symbol, atomic number, and atomic ...

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 ...

Stars are element factories, where elements constantly fuse or break apart to create other lighter or heavier elements. When we refer to light or heavy elements, we're talking about their atomic mass.

He soon had a table of 21 elements arranged by atomic mass, which he presented in a scientific paper the following month. Eventually, he had 36 different symbols. In his 1805 work, "A New System ...

Scientists believe that many of the elements found in the Universe that are heavier than iron are created when stars merge or explosively die, but they are still unsure about the cosmic origin of ...
