Elements along the steplike line have properties of both metals and nonmetals The least reactive elements are in the far right column Elements at the bottom of a column have more protons than elements at the top of a column O Nev O. The elements on the left side of a row have higher atomic mass than the clements on the right Need side from resour was t Next Don't s hecked at Submit Quiz 0 ip

Explanation / Answer

Last statement is false statement.

Atomic mass is increases with increasing atomic number.

Atomic number is increases in groups and periods. So atomic mass is increases from left to right and top to bottom.

Example:

Take 1 period elements

Hydrogen atomic mass 1.008 g/mol

Helium atomic mass 4.003 g/mol

From this clear that the elements on right side of the row has higher atomic mass than the elements on left side.

Hence correct option is,

The elements on the left side of the row have higher atomic mass than the elements on the right side.
