Which scientist proposed the model of an atom as a nucleus surrounded by electrons? james chadwick john dalton j. j. thompson ernest rutherford

The answer is Ernest Rutherford.

The correct answer will be option-Ernest Rutherford.

Explanation:

Atom is the smallest unit of matter which was earlier thought to be indestructible but later new findings suggested that atom contains sub-atomic particles.  

The arrangements of these sub-atomic particles in an atom were represented by many models, best accepted of which is presented by Ernest Rutherford in 1911.

His experimental findings concluded that a dense heavy nucleus is present in the center of an atom which is surrounded by a negatively charged nucleus.

Thus, the selected option is the correct answer.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
