the positive charge of the atom is uniformly distributed throughout the volume of the atom and the negatively charged electrons are embedded in it

the positive charge of the atom is uniformly distributed throughout the volume of the electron and the negative charge of electrons balances positive parts

the negative charge of the atom is uniformly distributed throughout the volume of the atom and the positively charged electrons are embedded in it

positive charge is concentrated at one place and negative charge is elsewhere.

Answer is:

the positive charge of the atom is uniformly distributed throughout the volume of the atom and the negatively charged electrons are embedded in it

Explanation:

According to 'plum pudding model' atoms on the whole are electrically neutral because the positive charge of the atom is uniformly distributed throughout the volume of the atom and the negatively charged electrons are embedded in it

2) Each element is associated with

Answer is:

with a characteristic spectrum of radiation

Explanation:

Each element is associated with with a characteristic spectrum of radiation

3) alpha particles used in Geiger-Marsden experiment were obtained from

Answer is:

Bi²¹⁴?Radioactive source

Explanation:

alpha particles used in Geiger-Marsden experiment were obtained from Bi²¹⁴?Radioactive source

4) In Geiger-Marsden experiment very small deflection of the beam was expected because

Answer is:

positive charge and the negative electrons are distributed through the whole atom reducing electric field inside the atom

Explanation:

In Geiger-Marsden experiment very small deflection of the beam was expected because positive charge and the negative electrons are distributed through the whole atom reducing electric field inside the atom
