increasing atomic

mass AND so that

elements in the same

row have similar

properties?

• Dmitri Mendeleev
• Albert Einstein
• Marie Curie
• Isaac Newton

Who rearranged the

elements by increasing

atomic number?

• Albert Einstein
• Marie Curie
• Isaac Newton
• Henry Mosely

Moseley's version is how the periodic table is arranged today?

• True

• False

What is the periodic law?

• The periodic law states that elements in the periodic table are arranged in order of decreasing atomic number.
• When elements

  are arranged in order of

  increasing atomic number,

  there is a periodic pattern in

  their physical and chemical

  properties.

• The periodic law states that elements in the periodic table are arranged in order of increasing atomic mass.
• The periodic law states that the physical and chemical properties of elements are not related to their atomic numbers.
