Synergy Atomic Structure

Developed the atomic theory. He said that all elements were made of unique atoms that were different from atoms of other atoms.

In his model of the atom, electrons travel around the nucleus in specific energy levels.

Proposed that the electrons of an atom were embedded in a ball of positive charge called the "plum pudding" model of the atom.

He established that the nucleus was: very dense, very small and positively charged. He also assumed that the electrons were located outside the nucleus.

Rutherford's experiment that led to discovery of the positively charged nucleus

According to this model, electrons are located in orbitals which are regions around the nucleus where electrons are likely to be found.

Smallest unit of an element that retains the properties of that element.

Pieces of matter that make up atoms.

Negatively charged subatomic particle that circles the nucleus of an atom.

Positively charged subatomic particle that is a part of the nucleus.

Neutral subatomic particle that is a part of the nucleus.

"Center" of the atom that is made up of protons and neutrons.

Region surrounding the nucleus where electrons are found.

Indicates the number of protons found in an atom of a specific element.

Indicates the number of protons and neutrons found in an atom of a specific element.
