Who is credited with creating the periodic table?

• Dmitri Mendeleev

• Antoine Lavoisier

• Marie Curie

• Albert Einstein

Henry Mosley's version of the periodic table exhibits definite patterns. These patterns have been evident in Mendeleev's table, but became more evident because Mosley's table

• was arranged by density of the elements

• was arranged by atomic number of the elements

• was arranged by state of matter of the elements

• had all 118 elements

Newlands' Law of Octaves was the first to suggest this phenomenon:

• periodicity

• fundamental repeats

• law of exponents
