(e) Ag

Step-by-Step Solution:
Step 1 of 3

Solution 52P

METALS

In the periodic table, you can see a stair-stepped line starting at Boron (B), atomic number 5, and going all the way down to Polonium (Po), atomic number 84. Except for Germanium (Ge) and Antimony (Sb), all the elements to the left of that line can be classified as metals.

Coming to sodium metal it is alkali metal having atomic number 11.and it has group number as IA.

Germanium

It is a metal and used as a semi conductor in transistors.Germanium is a chemical element with symbol Ge and atomic number 32. It is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. Pure germanium is a semiconductor with an appearance similar to elemental silicon. Like silicon, germanium naturally reacts and forms complexes with oxygen in nature. Unlike silicon, it is too reactive to be found naturally on Earth in the free (elemental) state.

Silicon

Silicon is a chemical element with symbol Si and atomic number 14. A hard...
