Answer 2

The subatomic particles in an atom are protons, neutrons, and electrons. Protons have a positive charge, are located in the nucleus, and have a mass of approximately 1 atomic mass unit (amu). Neutrons have no charge, are also located in the nucleus, and have a mass of approximately 1 amu. Electrons have a negative charge, are found in orbitals around the nucleus, and have a much smaller mass compared to protons and neutrons, approximately 1/1836 amu. Protons and neutrons are tightly packed together in the nucleus, while electrons occupy regions of space around the nucleus in various energy levels or orbitals.

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.
