Protons and Neutrons
Most of the space of an atom is just that. Space. The protons and neutrons make up most of the mass and are at the centre of the atom. The electrons orbit this central core in an electron 'cloud'. This cloud can be many orders of magnitude larger than the nucleus.

What did Rutherford conclude when most particles fired at metal passed straight through?
That the atom was mostly empty space
Which part of an atom takes up the most space?
The protrons and the neutrons take up the most space in a atom.The nucleus takes up the majority of the atoms mass but the majority of the atom at about 99.99% of the atom is actually empty space.
What these takes up the most space in an atom?
The thing that takes up the most space of an atom at about 99.99% of the size of the atom is empty space. The majority of the remaining 0.01% is found in the nucleus and about 0.00001% of the atom is taken by the electrons.
What was the conclusion of Rutherford's gold foil experiment in terms of an atom's mass and volume?
Rutherford found that when when he aimed alpha particles at a thin sheet of gold foil, that some of the particles were deflecteted and didn't go straight through the foil. The reason for this turned out the be that they ran into the nucleus. Most of the particles did go straight through, so Rutherford concluded that the atom was mostly empty space. He also concluded that the center of the atom contained the nucleus and had positively charged particles he called protons.
Which particles in an atom contribute most to mass of the atom?
The particles are protons, neutrons, and the nucleus inside of the atom Nice helping u >_<
What particles account for most of the space of the atom?
Protons and neutrons
Which subatomic particles are located in MOST of the space within an atom?
Protons and Neutrons
Does the nucleus occupy most of the volume in the atom?
No it does not.
What did Rutherford conclude when most particles fired at metal passed straight through?
That the atom was mostly empty space
What nucleus (protons and neutrons) make up most of the mass (weight) of the atom and occupy a small amount of space whereas the electrons weigh almost nothing but occupy a large amount of space?
A single electron has an infinitesimal volume; do not confuse with the electron cloud.
What is negatively charged that occupy most of the volume of the atom?
The electrons.
What part of an atom takes up most of its space?
The most space of an atom is vacuum.
How did Rutherford know that atom was mostly space?
Most of the particles went through the gold foil, but only a few bounced back.
What contributes to the most of the mass of an atom?
The majority of the volume in an atom is filled by the neutrons and the protons. Although the electrons do have a volume, they occupy significantly less space than the other two subatomic particles
What evidence led Rutherford to conclude that an atom is mostly empty space?
The experimental evidence led Rutherford to conclude that an atom is mostly empty space because most of the particles weren't deflected off of the gold foil in his experiment.
What subatomic particle occupies the cloudlike space that surrounds the atom's core?
The electrons occupy the electron cloud. It is not a cloud at all; it is simply a region where electrons are most likely to be found.
What were the conclusions and drawbacks of this gold foil experiment?
Ernest Rutherford, a New Zealander, designed an experiment to study how alpha particles, with a 2+ charge, interact with a piece of very thin gold foil. Rutherford bombarded a very thin piece of gold foil with a stream of postively charged particles known as the alpha particles. He found that most of the alpha particles passed straight through the foil. This shows that most of the atom is empty space. However, a few of the alpha particles bounced back and some of the alpha particles were defected. This means that the center of the atom, or nucleus, is positively charged because it repelled the alpha particles, the charge of which is positive. A direct collision repels an alpha particle backward. This shows that the center of the atom of gold is a tiny core heavier than an alpha particle. Rutherford concluded that an atom was made of a very dense, positively charged nucleus surrounded primarily by empty space in which the electrons could be found. The radius of the nucleus is extremly small, about 1/100 000 that of the atom itself. The volme of the atom is essentially the space that the electrons occupy. Now we know that the electrons move about the nucleus, not in a fixed location.
