Study Notes

Protons

Located in the nucleus of an atom.
Mass is approximately 1 atomic mass unit (amu).
Carries a positive charge.

Neutrons

Also located in the nucleus alongside protons.
Mass is roughly 1 amu.
Has no charge, thus neutrally charged.

Electrons

Found in electron clouds surrounding the nucleus.
Mass is negligible, often considered as zero.
Carries a negative charge.

Electron Clouds

First energy cloud holds up to 2 electrons.
Second energy cloud can accommodate 8 electrons.
Third energy cloud has a capacity of 18 electrons.

Neutron Calculation

Neutron count can be determined by subtracting the number of protons from the atomic mass number.

Isotopes

Defined as atoms with the same number of protons but differing numbers of neutrons.

Nucleus

Described as a small, dense, positively charged core of an atom made up of protons and neutrons.

Summary

Protons and neutrons are located in the nucleus, while electrons orbit in clouds.
Each particle has distinct charges and mass properties essential for atomic structure.
