Hi I am Lucas and I am going to take you through the history of the ATOM
Hi I am Democritus
All matter consists of atoms, which cannot be further subdivided into smaller particles.
Hi I am John Dalton and All matter is comprised of tiny, definite particles called atoms.Atoms are indivisible and indestructible.All atoms of a particular element share identical properties,
Hi I am Michael Faraday and Atoms have an electrical component. Electrical forces are responsible for the joining of atoms in compounds.
He thought that a point would be reached at which the cheese could not be cut into still smaller pieces. He called these pieces atomos, which means “uncuttable” in Greek.
He also believed that all compounds were composed of combinations of these atoms in defined ratios.Dalton also postulated that chemical reactions resulted in the rearrangement of the reacting atoms.
Hi I am Ernest Rutherford. the atom is mostly empty space, with nearly all of its mass concentrated in a tiny central nucleus. The nucleus is positively charged and surrounded at a great distance by the negatively charged electrons.
his discovery was crucial in allowing electricity to be transformed from a curiosity into a powerful new technology.
Faraday’s earliest experimental observations was a crucial precursor to the discovery of the first subatomic particle, the electron.
He discovered the electron and then went on to propose a model for the structure of the atom. His work also led to the invention of the mass spectrograph.
Hi I am JJ Thomson andAll atoms contain tiny negatively charged subatomic particles or electrons.
Although proven wrong Thomson's model was correct at the time, because it explained all that scientists then knew about the atom.
He also built the model of the atom that we all know today. He had the negatively charged electrons surround the nucleus of an atom.
