Why did Thompson choose a circle for his first model of the atom?
The electron will always be the same distance from the nucleus. If there is a heavy part, it makes sense that it will be in the middle so that the atom will be symmetrical. Solar systems are similar in that there is a dense part and a lot of empty space with the sun in the middle.
Why Rutherford's model of the atom is called the nuclear atom?
The Rutherford model was called the nuclear model because he decided on the atom to consist of both the nucleus, and the orbits of electrons, so he separated the nucleus from being combined with the whole atom. it is a due to his test of gold foil being shot with a cathode ray, and since most of the electrons went right through the gold foil, he assumed that the atom was filled with mostly empty space, and that is why the modern description of an atom has a huge size for where the electrons ought to be, with such a small nucleus.
What part of an atom carries most of its mass?
The vast majority of an atom's mass is within the nucleus; the electrons orbiting the nucleus, which do contain the same amount of charge as the nucleus(albeit negative), have virtually no mass when compared to the nucleus. In fact many scientific disciplines disregard the mass of electrons altogether.
Why are protons and neutrons not involved in chemical reactions?
Hate to burst your bubble, but they are, considering that the structure of the nucleus is what gives the electrons their properties. That's kind of like asking, "why isn't sunlight part of the taste of a fruit?"I think the question should be why are the electrons mainly responsible for chemical reactions? On the atomic scale, the atom is mostly empty space, with the electron being very far away from the nucleus. The first part of the atom to interact with another atom would always be an electron. The way that atoms share electrons is a big factor in chemical reactions.
What did ernest rutherford conclude about the nucleus of an atom?
Ernest Rutherford concluded that the positive charge of an atom is concentrated in a dense core at the center called the nucleus. This discovery came from his gold foil experiment, where he observed that most of the alpha particles passed straight through the foil, indicating that most of the atom is empty space.
How much of an atom is relatively solid?
An atom is mostly empty space, with the solid part being the nucleus composed of protons and neutrons. Electrons orbit the nucleus in electron clouds, giving atoms their volume. Therefore, the solid part of an atom (nucleus) makes up a very small fraction of its overall volume.
What is the most part of the volume of the atom made of?
A great, great amount of empty space. I refer you to the link attached.
What did rutherford's gold foil experiment show?
Rutherford's gold foil experiment showed that atoms have a small, positively charged nucleus at the center, surrounded by mostly empty space where electrons orbit. This disproved the "plum pudding" model of the atom and led to the development of the planetary model of the atom.
What fills the space in between gas molecules Is it just empty space?
The space in between gas molecules is not "just empty space." It is filled with constantly moving and colliding molecules. Gas molecules are in constant motion, so even though there may be more space between them compared to liquids or solids, the space is not truly empty.
What part of the nucleus did Rutherford add to the atom model?
Rutherford added the concept of a dense, positively charged nucleus at the center of the atom, with electrons orbiting around it in a mostly empty space. This model became known as the Rutherford model of the atom.
What part of an atom takes up most of its space?
The most space of an atom is vacuum.
What is a negatively charged part of an atom?
Electrons are negatively charged sub atomic particles.
Why did Thompson choose a circle for his first model of the atom?
The electron will always be the same distance from the nucleus. If there is a heavy part, it makes sense that it will be in the middle so that the atom will be symmetrical. Solar systems are similar in that there is a dense part and a lot of empty space with the sun in the middle.
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 does the word mostly empty mean in science?
In science, there is no true vacuum (empty space). "Mostly empty" means a non-significant number greater than zero in the given content. For example, if we had a zoo of 9,999 elephants and 1 lion, we could say my zoo is "mostly elephants". However, if 9,997 elephants died, leaving 2 elephant and 1 lion, we can no longer say it is "mostly elephants" as the lion represents a large part of the total zoo.
What part of the atom makes up most of the volume?
most of an atoms volume is nothing, think of the atom as a football stadium, a football in the centre is the neucleus, electrons would be the size of peas in the very back row, the rest is empty space. on top of that the neclues is made of protons and neutrons, which spaces between, these necleons are made of quarks which also have empty space between them, the quarks are made of neons which again have spaces between. Many physicists believes this continues in this fashion.
What region of an atom has the least mass?
The space surrounding the nucleus.
