Empty space makes up most of the atom which the negatively charged electrons use to orbit around the positively charged nucleus. The nucleus is made up of positively charged protons and neutral neutrons. The atom also has an electron cloud which is made up of, yes you guessed it, electrons

What was the significance of Rutherford's experiment?

Rutherford's experiment, known as the gold foil experiment, led to the discovery of the atomic nucleus and the development of the nuclear model of the atom. This experiment provided evidence that most of the atom's mass and positive charge is concentrated in a small, dense nucleus at the center of the atom, with electrons orbiting around it. It revolutionized our understanding of atomic structure.


Who first came up with the idea that the atom is mostly empty space?

The idea that the atom is mostly empty space was first proposed by Ernest Rutherford based on his gold foil experiment in 1909. This experiment led to the discovery that most of an atom's mass is concentrated in a nucleus at the center, surrounded by electrons in vast empty space.


What is composed mostly of the protons and neutrons in the nucleus?

The nucleus of an atom is composed mostly of protons and neutrons. Protons have a positive charge and neutrons have no charge, together they make up the majority of an atom's mass.


What is in side an atom?

An atom is composed of a nucleus containing protons and neutrons, surrounded by electrons orbiting in energy levels. The protons and neutrons are located in the nucleus at the center of the atom, while the electrons are found in the electron cloud surrounding the nucleus.


What did Rutherford conclude when most particles fired at metal passed straight through?

Rutherford concluded that atoms must be mostly empty space with a small, dense nucleus at the center. This discovery led to the development of the Rutherford model of the atom.
