Density:
* Extremely high: The nucleus contains nearly all the mass of an atom, packed into a tiny space. This makes it incredibly dense, about 10^14 to 10^17 times denser than water.
* Example: A teaspoon of nuclear matter would weigh billions of tons!
* Comparison: Imagine squeezing all the mass of Earth into a sphere the size of a grapefruit. That's roughly the density of a nucleus.
Charge:
* Positive: The nucleus contains protons, which have a positive charge.
* Number of protons: The number of protons in a nucleus determines the element. For example, all carbon atoms have 6 protons, all oxygen atoms have 8 protons, and so on.
* Neutral atom: The positive charge of the nucleus is balanced by the negative charge of the electrons orbiting the nucleus, making a neutral atom.
Key takeaways:
* The nucleus is the tiny, dense core of an atom.
* It contains nearly all the atom's mass.
* Its positive charge comes from the protons within it.
* The number of protons defines the element.
