ATOMIC STRUCTURE STUDY GUIDE AND OR NOTES:
Elements- There are 188 elements on the periodic table mainly consisted of
metals,transition metals,non metal, and metalloids
Protons-Located in the nucleus with a charge of plus one which identifies the element
and also has an appreciable mass which weighs almost as much as a neutron
Neutrons-Located inside the nucleus and has no charge which means zero charge, and it
has an appreciable mass which weighs more than other subatomic particles.
Electrons-Located outside of the nucleus with a charge of negative one and has a
negligible mass which weighs less than other particles and takes around 2000 electrons
to weigh as much as a proton or neutrons.
Atoms-Atoms are the smallest particles of an element that still retains the properties of
the element. And if the number of protons and electrons in order to be neutral
Mass Number- Number of protons and neutrons in the nucleus
- Each element's atoms differ in the number of protons, neutrons and electrons.
They contain the atomic number of an element refers to the number of protons
and nucleus of those atoms. The number of electrons for a neutral atom is equal
to the number of protons; the number of neutrons in an atom varies and cannot be
predicted using the periodic table.
- Electron has a negative one charge and is the lightest of the subatomic particles
- Proton has a plus one charge and is the second heaviest subatomic particle
- Neutron has a zero charge and is the heaviest sub atomic particle
The Billiard Ball Model was made by John Dalton and made it clear atoms are a ball like
structure
The Plum Pudding model was made by JJ Thompson, which discovered atoms were
made up of smaller components and also discovered electrons which was also compared
to a chocolate chip cookie
The Electron Cloud model was made by Erwin Schrödinger and Weber Heisenberg which
showed where electrons could be found around the atoms nucleus
