Question

The model of an atom according to which “An atom contains negatively charged particles called electrons embedded uniformly throughout a thinly spread positively charged spherical mass” is

• A. Bohr’s atomic model
• B. Rutherford’s model of an atom
• C. Thomson’s atomic model
• D. Nuclear model of an atom

Answer 1

The correct option is C Thomson’s atomic model

According to Thomson’s model of an atom, an atom consists of positively charged sphere. The positive charge in the atom is spread all over like the red edible part of a watermelon, while the electrons are embedded in the positively charged sphere, just like the seeds in the watermelon. Since negative and positive charges are equal in magnitude, they balance each other and thus, the atom becomes electrically neutral as a whole.
Hence, the correct answer is option (c).
