SUMMARY

An atom is composed of a nucleus containing protons and neutrons, surrounded by electrons. The atomic number, defined by the number of protons, determines the element type, such as hydrogen, helium, or carbon. Regular hydrogen is unique as it typically contains no neutrons. The balance of protons and electrons defines a neutral atom, while the combination of protons and neutrons determines the isotope.

PREREQUISITES
  • Understanding of atomic structure
  • Familiarity with basic physics concepts
  • Knowledge of isotopes and atomic numbers
  • Basic comprehension of electron configuration
NEXT STEPS
  • Study the structure of atoms in detail using "Concepts of Modern Physics" by Arthur Beiser
  • Explore the periodic table and its significance in chemistry
  • Learn about isotopes and their applications in "Introduction to Nuclear Physics"
  • Watch educational videos on atomic theory on YouTube, focusing on channels like CrashCourse
USEFUL FOR

Students of physics, chemistry enthusiasts, and anyone seeking to understand the fundamental components of matter and atomic theory.

I'm trying to find a way to understand Q.P.
So far I know that each element contains as many protons as it does nuetrons or electrons. Is that right?
Derp lol

No. For instance, hydrogen usually does not contain neutrons at all.
 
An atom is made up of a nucleus, which is positively charged, surrounded by electrons. The nucleus is made up of protons and neutrons (with the exception of regular hydrogen, as pointed out by Demystifier). The number of protons, known as the atomic number, determines the charge of the nucleus and the element (hydrogen, helium, carbon, etc.) The number of protons and neutrons determine the isotope. For a neutral atom, the number of negatively charged electrons must be equal to the number of positively charged protons in the nucleus.

Depending on your level, I suggest that you get a good textbook in physics. There are also many instructive videos on YouTube. Hyperphysics is also a good resource: http://hyperphysics.phy-astr.gsu.edu
