chapter 5 section 1 Flashcards
in developing his periodic table, Mendeleev listed on cards each element’s name, atomic mass, and
properties
Mendeleev’s periodic table did not list all elements in order of increasing atomic mass because he grouped together elements with similar
properties
Mendeleev predicted that the gaps in his periodic table represented
undiscovered elements
the person whose work led to a periods table based on increasing atomic number was
moseley
the periodic law states that the physical and chemical properties of elements are periodic functions of their atomic
numbers
which group of elements was discovered by Strutt and Ramsay
noble gases
a repeating pattern is referred to as
periodic
on most periodic tables, the lanthanides and actinides appear
below the main portion
what is the difference in atomic number between He and Ne
8
which noble gas has the greatest atomic number
