Periodic table

The Elements on the Periodic Table are arranged in order of increasing

• atmoic mass

• molar mass

• atomic number

• oxidation number

Which element has chemical properties that are most similar to the chemical properties of sodium

• beryllium

• calcium

• lithium

• magnesium

Atoms of metallic elements tend to

• gain electrons and form negative ions

• gain electrons and form positive ions

• lose electrons and form negative ions

• lose electrons and form positive ions

Which element has atoms with the largest atomic radius?

• Rb

• Cs

• Sr

• Ba

Which list of elements contains a metal, a metalloid, a nonmetal, and a noble gas?

• Be, Si, Cl, Kr
