5.1 Flashcards
Definition of isotope
Having an extra neutron.
Which charges attract or repel
Attract + and -
Repel - and -
The relationship between coulombic attraction and the amount of charge
If you times the amount of charge by x, you times the coulombic attraction by x.
The relationship between coulombic attraction and distance
If you times the amount of charge by x, you times the coulombic attraction by 1/x.
Protons Neutrons and Electrons.
Protons +1, heavy, nucleus, and element
Neutrons 0, heavy, nucleus, and hold together.
Electrons -1 almost 0, moving, chemical reaction/bonds.
Pick which atom has a stronger or weaker attraction for valence electrons and explain why
O>N because have more protons.
Explain why isotopes can be useful in scientific research
Learning the life of an organism.
Oxygen has
8 protons, 8 neutrons, 8 electrons and no charge.
Why do protons not stick together?
They repel each other.
