Why did Mendeleev leave empty spots in his periodic table (pg. 10)?

• he knew there would be elements discovered that fit there

• he didn't know what to put there so he just left them empty

• there needed to be spaces so that the other elements weren't so close together

Why don't some of the element names and symbols match (pg. 11)?

• some of the element names are from a different language that does match the symbol

• there were no more options left to give them symbols so scientists just made them up

• the symbols matched the country name that they were discovered in

Which of these parts of an element box gives you the number of protons (pg. 11)?

• atomic number

• atomic mass

• element name

• element symbol
