Context: Physics
Definition2: electron around
Conjdef: A piece with
Intuition: smallest piece of an element that can exist and still be recognized as that element.

Name: electron
Definition: with electric charges

Chapter: 1
Definition2: in the outer region of the atom
Conjdef: lightweight particles

Name: nucleus
Definition: in the center

Chapter: 1
Definition2: with all the mass
Conjdef: Part of the atom
Definition3: with positive electrical charge
Definition4: made of protons and neutrons

Name: proton
Definition: positively charged

Chapter: 1
Conjdef: Part of the nucleus

Name: neutron
Definition: without electrical charge

Chapter: 1
Conjdef: Part of the nucleus

Name: hydrogen
Definition: An atom consisted of a single proton and a single electron

Question: What differentiate atoms ?
Answer: Their number of proton.

Chapter: 1

Name: the strong force
Definition: force allowing proton in the same nucleus to stay together

Chapter: 1

Question: why is there a limit to the size of the nucleus of stable atoms ?
Answer: When there are two many nucleus, the strong force can't counter-balance repulsive electrical force

Chapter: 1

Question: How to have bigger nucleus without changing the atom's name
Answer: Adding neutron. Since they add strong force and no repulsive electrical force
