What does 180 degree deflection of only very few alpha particles indicate? *
1 point
A large space in an atom is mostly empty
Electrons in an atom revolve around the positively charged protons
The positive charge and mass of the atom is concentrated at the center of the atom
Atoms have positively and negatively charged species that are at the center of the atom

Answer:
Very few particles were deflected from their path, indicating that the positive charge of the atom occupies very little space.
Atoms are not mostly empty space because there is no such thing as purely empty space. Rather, space is filled with a wide variety of particles and fields. ... It's true that a large percentage of the atom's mass is concentrated in its tiny nucleus, but that does not imply that the rest of the atom is empty.
Electrons contribute greatly to the atom's charge, as each electron has a negative charge equal to the positive charge of a proton. Scientists define these charges as “+1” and “-1. ” In an uncharged, neutral atom, the number of electrons orbiting the nucleus is equal to the number of protons inside the nucleus
According to Rutherford, positive charge is concentrated in the center of the atom, called nucleus.
All atoms have the same number of electrons as protons, so the positive and negative charges "cancel out", making atoms electrically neutral. Unlike protons and neutrons, which are located inside the nucleus at the center of the atom, electrons are found outside the nucleus.
This indicates that most of the space in an atom is empty and the positive charge is concentrated in a much small area which is called as nucleus.This cause repulsion to positively charged alpha-particles
