Question

Following Dalton’s theory, scientist were curious to know the answer of the question:

What would atoms look like if we could see them?

Answer 1

Atoms have no colour, and the colours in diagrams are only for illustration. According to Rutherford's model, an atom is mostly empty space with a tiny, dense, positively charged nucleus at its centre, and electrons move around it. If an atom were the size of a cricket ground, the nucleus would be only about the size of a black pepper grain. Today, electrons are understood to exist as electron clouds around the nucleus.
