an atom is made out of sphere of positive changes with negativity charge electron embedded in it
Answer (1)
This describes the Plum Pudding Model by J.J. Thomson. He said an atom is like a positive sphere with negative electrons embedded in it. Imagine a round cake (the positive charge) with raisins inside (the negative electrons). This idea helped scientists understand that atoms have parts inside, but later models improved it, like Rutherford’s model with a nucleus.
