The Periodic Table

 Who came up with the idea of organizing all the known elements?

• Mendeleev

• Moseley

 While studying the physical and chemical properties of the elements, Mendeleev found that these properties repeated in predictable patterns based on an element's what?

 Today, what do we call the arrangement of elements?

The modern periodic table is arranged by an increasing what?

• atomic mass

• atomic number

The modern periodic table uses this man’s arrangement of the elements.

• Mendeleev

• Moseley

The periodic table orders elements horizontally by the number of these in the atom’s nucleus.

• neutrons

• protons

The periodic table places those elements with similar chemical properties in these.

• columns/groups

• periods
