What are the three subatomic particles that make up an atom?
electrons, protons, neutrons
What are the charges of electrons, protons, and neutrons?
electrons - negatively charged, protons - positively charged, neutrons - uncharged
Which laws could Dalton's atomic theory explain?
law of conservation of mass, law of constant composition, law of multiple proportions
What did experiments towards the end of the nineteenth century reveal about Dalton's atomic theory?
An atom is not the smallest or indivisible particle of matter as stated by Dalton; it is made up of even smaller particles.
What did Dalton's atomic theory propose about the nature of the atom?
Dalton's atomic theory proposed that the atom is the smallest indivisible constituent of all matter.
What were the three laws that Dalton's theory could explain?
Dalton's theory could explain the law of conservation of mass, law of constant composition, and law of multiple proportions.
What were the smaller particles that experiments towards the end of the nineteenth century revealed the atom to be composed of?
Experiments revealed that the atom is composed of smaller particles called electrons, protons, and neutrons.
What are the charges of electrons, protons, and neutrons?
Electrons are negatively charged, protons are positively charged, and neutrons are uncharged in nature.
How did the discoveries towards the end of the nineteenth century challenge Dalton's atomic theory?
The discoveries showed that an atom is not the smallest or indivisible particle of matter as stated by Dalton, and that it is made up of even smaller particles.
