What else can I help you with?
Are subatomic particles found inside atoms?
Yes, atoms contain subatomic particles.
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 includes protons neutrons and electrons?
Atoms are the physical things that contain all these particles. The general term for all of them is Subatomic Particles.
Does carbon atoms contain molecules?
No. A Carbon atom, like all atoms, only contain Subatomic Particles. A Molecule is a chain of atoms linked together with an atomic bond.
Are electrons made up of 1 atom?
No. Electrons are subatomic particles, meaning they are smaller than atoms. Atoms contain electrons, not the oter way around.
What are molecules and their subatomic particles?
Molecules contain atoms and these atoms contain subatomic particles.
Are subatomic particles found inside atoms?
Yes, atoms contain subatomic particles.
Did Dalton know that atoms contain subatomic particles?
No, Dalton believed that atoms were indivisible.
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 observations led scientists to propose the existence of subatomic particles?
Atoms were found to be divisible after all . But scientists discovered that the atoms were made of smller perticles , called subatomic particles.
What The first subatomic particle discovered?
Subatomic particles are particles that are smaller than atoms. There are two different types of subatomic particles: elementary particles and composite particles. The first subatomic particle that was discovered was the electron. It was first theorized to exist by G. Johnstone Stoney in 1874 and was confirmed to exist in 1897 by J.J. Thomson.

What is the isotope symbol for atoms that contain the numbers of subatomic particles of 2 protons and 1neutron?
2He3
What are the three subatomic particles of a molecule?
The three subatomic particles of a molecule are protons, neutrons, and electrons. Protons carry a positive charge, neutrons are neutral, and electrons carry a negative charge. Together, they make up the structure of an atom.

Subatomic particles bigger than molecles?
Subatomic particles are smaller than molecules and are the building blocks of atoms. Protons, neutrons, and electrons are examples of subatomic particles found in atoms. There are no known subatomic particles that are bigger than molecules.
