The heavy, dense nucleus of the atom caused the alpha particles to bounce back in Rutherford's experiment.
What else can I help you with?
What part of a atom causes particles to bounce back?
The positively charged nucleus of the atom, which contains protons and neutrons, is what causes particles to bounce back due to electrostatic repulsion. When an incoming particle has the same charge as the nucleus, such as another positively charged particle, they will repel each other, causing the incoming particle to bounce back.
What do we call the neutral part of atoms?
Particles in an atoms nucleus which do not have electric charge are Neutrons.
What are electrons a part of?
Electrons are a part of atoms. They are subatomic particles that orbit around the nucleus of an atom and carry a negative charge. Electrons are involved in various chemical reactions and play a crucial role in the behavior of matter.
What are electrons part of?
electrons are part of atoms.
Why did J Thomson reason that electrons must be a part of the atoms of all elements?
Cathode rays are negatively-charged particles.
What subatomic particle is not part of the nucleus?
Atoms are the building blocks of matter. Atoms are made up of electron, neutron and proton particles. Electrons are negatively charged, neutrons are neutral and protons have a positive charge.
What part of Dalton's theory of was disproved when scientists discovered that atoms contain protons electrons and neutrons?
John Dalton believed that atoms were the fundamental building blocks of matter, and that they could not be created, destroyed or split. However he was wrong, because atoms are made out of subatomic particles such as Protons, Neutrons and Electrons - and later still, it was discovered Protons and Neutrons too are made of even smaller particles.
What aurora borealis is caused by the blank which is a part of the atmosphere?
Charged particles from the Sun striking the upper atmosphere.
What aspect of Dalton's theory was not supported by Thomsons findings?
Dalton's theory proposed that atoms are indivisible and have no subatomic particles, which was not supported by Thomson's discovery of the electron. Thomson's findings showed that atoms contain subatomic particles, challenging the notion of indivisible atoms in Dalton's theory.
What is the smallest part of a ele ment?
You probably mean the smallest part of an atom. That would be an electron, because electrons are the particles making up atoms that are smallest in size.
Which is not part of John Dalton atomic theory?
Atoms are made up of smaller particles.
When The aurora borealis is caused by the which is a part of the thermosphere.?
The aurora borealis, or northern lights, is caused by the interaction of charged particles from the solar wind with the Earth's magnetic field and atmosphere, specifically in the thermosphere. When these high-energy particles collide with gases like oxygen and nitrogen, they excite these atoms, resulting in the beautiful light displays we see. The thermosphere, located between about 85 km to 600 km above the Earth's surface, plays a crucial role in this process as it contains the ionized particles necessary for the auroras to occur.
