An element has an atomic number of 30. How many protons and electrons are in a neutral atom of the element?
Owen AmbroseThere are 30 protons and 30 electrons.
The atomic number gives the number of positively charged protons in an atom or element.
The number of protons is always equal to the number of electrons in a neutral atom.
The positive charge on the proton is canceled by the negative charge on the electron leaving a neutral atom.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
