Flashcards
What is the nucleus?
What is the nucleus?
The central part of an atom, containing protons and neutrons. It holds most of the atom's mass.
What are protons?
What are protons?
Subatomic particles with a positive charge, located in the nucleus. They determine the element's atomic number.
What are neutrons?
What are neutrons?
Subatomic particles with no charge, located in the nucleus. They contribute to the atom's mass.
What are electrons?

Study Notes
Atomic Structure
- Atoms have a central nucleus containing protons and neutrons.
- Electrons orbit the nucleus in shells.
- The nucleus is extremely small compared to the overall atom (much smaller than a bacterium or human hair).
- Protons are positively charged subatomic particles.
- Neutrons are uncharged subatomic particles.
- Electrons are negatively charged subatomic particles with negligible mass relative to protons and neutrons.
- Most of an atom's mass is concentrated in the nucleus due to the presence of protons and neutrons.
- Relative mass of a proton is 1.
- Relative mass of a neutron is 1.
- The charges of protons and electrons are equal and opposite.
Subatomic Particle Masses
- Subatomic particle masses are extremely small.
- Rather than using absolute kilogram values, relative masses are used.
- Relative mass is how many times heavier a particle is compared to another.
