What was significant about the gaps in Mendeleev's table?

What was the basis for arranging the elements in Mendeleev's table?

Atomic mass

Density

Melting point

Atomic number

In Mendeleev's periodic table, elements were arranged in increasing...?

Density

Atomic mass

Atomic number

Reactivity

Mendeleev left gaps in his table for...?

Transition metals

Isotopes

Noble gases

Undiscovered elements

Who developed the first attempt at organizing elements?

Bohr

Rutherford

Mendeleev

Dobereiner

Dobereiner grouped elements into triads based on property similarities. True/False?

Maybe

True

False

Not sure

What was the basis of Dobereiner's triads?

Equal size

Similar chemical properties

Same weight

Opposite charges

Dobereiner's triads were limited by the number of known elements. True/False?

Maybe

Not applicable

True

False

Who proposed the Law of Octaves in early periodic systems?

John Newlands

Dimitri Mendeleev

Johann Wolfgang Döbereiner

Lothar Meyer

Newlands' periodic law organized elements based on what repeating pattern?

Octaves

Periods

Groups

Atomic mass

What was a major limitation of Newlands' periodic table model?

Left no gaps for undiscovered elements

Not organized by atomic number

Elements listed in decreasing atomic mass

Did not follow a specific repeating pattern

Why did many scientists reject Newlands' work on the periodic table?

Did not account for isotopes

Lack of scientific evidence

Poor ordering of elements

Incorrect atomic masses

Associate the scientist with the evolution of the periodic table.
