1. Protons:
* Relative Mass: 1 amu (atomic mass unit)
* Relative Charge: +1
* Location: Inside the nucleus of the atom.
2. Neutrons:
* Relative Mass: 1 amu (approximately the same as protons)
* Relative Charge: 0 (neutral)
* Location: Inside the nucleus of the atom, alongside protons.
3. Electrons:
* Relative Mass: Negligible (about 1/1836 amu compared to protons and neutrons)
* Relative Charge: -1
* Location: Orbiting the nucleus in a cloud of probability called an electron cloud. The specific energy levels and shapes of these orbitals are defined by quantum mechanics.
Key Points:
* Atomic Number: The number of protons in an atom's nucleus determines its atomic number and identifies the element.
* Mass Number: The sum of protons and neutrons in an atom's nucleus determines its mass number.
* Isotopes: Atoms of the same element can have different numbers of neutrons, resulting in isotopes. Isotopes have the same atomic number but different mass numbers.
* Neutrality: In a neutral atom, the number of protons (positive charge) equals the number of electrons (negative charge). This results in a net charge of zero.
How to Remember:
* Protons: Think of them as the "positive" particles in the "proton" nucleus.
* Neutrons: Think of them as the "neutral" particles in the "neutron" nucleus.
* Electrons: Think of them as the "negative" particles "electron"ically orbiting the nucleus.
