It is considered the smallest particle of matter.

It is a representation of what an atom could look based on observations and scientific evidence that descrive how atoms behave

Who discovered electrons?

It is a glass tubing with two electrodes, namely, the anode and the cathode at each end. It is used by Joseph John Thomson to discover electrons

They are negatively charged particles

It is also called the chocolate-chip cookie model.

He used the ratio determined by J.J. Thomson to measure theactual charge of an electron through his oil drop experiment

Who discovered the nucleus and the proton through their now-famous gold foil experiment?

It is the dense core that the atom consists

It is a positively charge particle in the nucleus

Rutherford described that the atom consits of a dense core called the nucleus with a positively charge particle in it known as the proton, while electrons surround the nucleus. He called this the __________

Niels Bohr improved the idea of Rutherford by proposing that electrons are not stationary as they move around the nucleus in fixed circular orbits known as energy levels. He called this new model the __________

He worked on the experiment where berrylium was bombarded with alpha particles that emitted a stream of radiation, which he thought to be gamma radiation

It is equivalent to the number of protons in its nucleus

It is the combined number of protons and neutrons present in its nucleus

We can use the __________ of an element by using its chemical symbol and represent it with its corresponding atomic number and mass number

This is what you call to electrically charged atoms

If an atom gains an electron it will then become negatively charged because there are more electrons than the protons. This is called ___________

If the atom loses an electron, it will become positively charged as there are more protons than electrons. This is called ___________

These are atoms of the same element that have the same number of protons and electrons but have different number of neutrons

What are the three basic subatomic particles

What are the five atomic theories
