Chemistry Test 2- The History And Arrangement Of The Periodic Table 5

Members of which group easily lose an electron to form a +1 cation? halogens alkaline earth metals noble gases alkali metals

Which property would cesium most likely have? It is hard. It is ductile. It is a gas. It has low reactivity.

Which element is placed in the same period as ruthenium but has a higher atomic number than it? bismuth osmium silver zirconium

How was the work of Newlands similar to that of Mendeleev on the periodic table? They both arranged the elements in order of increasing atomic mass. They both arranged elements that had similar properties into groups. They both predicted the positions of undiscovered elements on the table. They both placed the relative atomic mass of each element on the table.

Which is another name for groups of elements? actinides families halogens periods

Which element is a halogen? argon bromine calcium lithium

Which element is classified as a noble gas? O N Cl Xe

How did Moseley establish a more accurate periodic table? by arranging the elements according to atomic mass instead of atomic number by arranging the elements according to atomic number instead of atomic mass by arranging the elements into horizontal periods by arranging the elements into vertical groups

Moseley made revisions to the periodic table that resolved some of the problems with Mendeleev's version. Which of these was a result of his revisions to the periodic table? The revised periodic table could account for the discovery of new elements. The revised periodic table could account for variations resulting from isotopes. Scientists could begin to write new information onto each element. Scientists could begin to place the table on a single sheet of paper.

Which element has the greatest average atomic mass? iodine bromine tellurium krypton

Who wrote the first modern chemical textbook? Antoine Lavoisier Dmitri Mendeleev Henry Moseley Johann Dobereiner

What is the chemical symbol for magnesium? Mo Mn Mg Md

Moseley made revisions to the periodic table that resolved some of the problems with Mendeleev's version. Which of these was a result of his revisions to the periodic table? The revised periodic table could account for the discovery of new elements. The revised periodic table could account for variations resulting from isotopes. Scientists could begin to write new information onto each element. Scientists could begin to place the table on a single sheet of paper.

Which is classified as an inner transition element? calcium copper fermium helium

Which scientist established the law of octaves? Antoine Lavoisier Dmitri Mendeleev Henry Moseley John Newlands

Who is credited with creating the first periodic table? Johann Dobereiner Henry Moseley Dmitri Mendeleev John Newlands

How did the work of Dmitri Mendeleev differ from that of John Newlands in the development of the periodic table? Mendeleev arranged the elements according to increasing atomic mass. Mendeleev predicted elements that would later be discovered. Mendeleev identified elements that had similar properties. Mendeleev organized elements into triads based on their properties.
