General Science GK Questions for Competitive Exams

Science comes from the Latin word" Scientia" meaning" knowledge" and thus the term General Science GK will be described because wisdom is associated with the miracle we regularly encounter in our way of life. Currently, styles of abstract questions are asked within the examinations supported by introductory generalities of drugs, Chemistry & Biology. General Science GK Questions supported life marvels are more important for all competitive examinations.

(A) 17

(B) 19

(C) 36

(D) 53

Explanation :

An atom of an element has atomic number 17 and mass number 36. The number of neutrons in its nucleus is 19.

Q :

The mobility of conduction band electrons is greater than that of holes because

(A) they are light

(B) they collide less often

(C) they have negative charge

(D) they require less energy to move

Explanation :

In a semiconductor the mobility of electrons (referring to 'conduction electrons' or 'free-electrons') is greater than that of a holes (indirectly referring to 'valence electrons') because of different band structure and scattering mechanisms of these two carrier types

Q :

The chemical behaviour of an atom depends on its:

(A) on the number of protons in the nucleus

(B) on the number of neutrons in the nucleus
