Question

which of the following can be deduced from the periodic table? a.many physical properties of elements. b. distribution of various isotopes. c. time of discovery. d. age of a sample of elements

Answer 1

Answer:

Many physical properties

Explanation:

• The periodic table of elements arranges elements into columns called groups and rows called periods.
• Elements in the same period have the same number of energy levels while those in the same group share similar chemical properties.
• From the periodic table, one can deduce many physical properties of elements. For example, the physical state, the valence electrons, atomic radius, etc.
• Elements in the same group have the same number of valence electrons and as you go down the group the energy levels increase thus increasing the atomic radius.
• Additionally, from the periodic table, one can identify whether an element is a metal, non-metal or a metalloid.
