Key Takeaways: Isotopes
Isotopes are samples of an element with different numbers of neutrons in their atoms.
The number of protons for different isotopes of an element does not change.
Not all isotopes are radioactive. Stable isotopes either never decay or else decay very slowly. ...
When an isotope decays, the starting material is the parent isotope.
Explanation:
Acceleration, a = (v - u)/t
where v is the final velocity, u is the initial velocity, and t is the time.
This formula on a velocity time graph represents the slope of the graph.
Answer:
They both describe atoms as being made up of positive and negative matter.
Explanation:
In both Bohr's model and Thomson model, the atom consists of positively-charged matter and negatively-charged matter. However, the structure of the atom in the two models is totally different:
- in Thomson's model, the atom consists of a large sphere of uniform positive charge, and electrons (which are negatively charged) are scattered all around inside this sphere
- In Bohr's model, the atom consists of a small, positively charged nucleus, while the electrons (negatively charged) orbit around the nucleus in precise orbits.
