The cathode ray was deflected away from the negatively-charged electric plate and towards the positively-charged plate. This indicated that the cathode ray was composed of negatively-charged particles.


He concluded that the atom can be divided into smaller particles.]]> 2023-09-29 02:26:30 UTC https://padlet.com/3884072/mto9c7ba4dqgldqm/wish/2725497699 Dalton believed that atoms were solid, mass filled, hard, impenetrable, movable particles 3884072 https://padlet.com/3884072/mto9c7ba4dqgldqm/wish/2725499909 Dalton's experiment of combining oxygen with volumes of nitric oxide in a covered container over water.

Dalton proposed that every single atom of an element, such as gold, is the same as every other atom of that element.]]> 2023-09-29 02:29:58 UTC https://padlet.com/3884072/mto9c7ba4dqgldqm/wish/2725499909 Rutherford described it as having a tiny, dense, and positively charged core called the nucleus. 3884072 https://padlet.com/3884072/mto9c7ba4dqgldqm/wish/2725503489 Rutherford's experiment consisted of A beam of alpha particles was aimed at a piece of gold foil. Most alpha particles passed through the foil, but a few were scattered backward. This showed that most of the atom is empty space surrounding a tiny nucleus.

Rutherford's conclusion is that the atom is mostly empty space, with nearly all of its mass concentrated in a tiny central nucleus]]> 2023-09-29 02:35:20 UTC https://padlet.com/3884072/mto9c7ba4dqgldqm/wish/2725503489 Bohr's description was that electrons revolve around the positively charged nucleus in a definite circular path called orbits or shells. 3884072 https://padlet.com/3884072/mto9c7ba4dqgldqm/wish/2725505896 Bohr's conclusion is that electron will have more energy if it is located away from the nucleus whereas electrons will have less energy if it located near the nucleus.]]> 2023-09-29 02:38:50 UTC https://padlet.com/3884072/mto9c7ba4dqgldqm/wish/2725505896 Heisenberg's description was the same as Rutherford's 3884072 https://padlet.com/3884072/mto9c7ba4dqgldqm/wish/2725509635 Heisenberg's experiment included trying to measure the position of an electron with a gamma ray microscope.


Heisenberg's conclusion is that the linear momentum and the position of an electron or other subatomic particle, it is not possible to simultaneously predict the value of both variables.]]> 2023-09-29 02:44:02 UTC https://padlet.com/3884072/mto9c7ba4dqgldqm/wish/2725509635
