Atomic structure Flashcards
What is and atom
The smallest part of an element that can exist
What is the nucleus
The central part of the atom
What is a proton
Positively charged particles found in the nucleus
What are neutrons
Uncharged particles found in the nucleus
What is an electron
Negatively charged particles found in energy levels around the nucleus
How can u find the atomic number
Atomic number = no. Protons
How do you find the mass number
Mass number = no. Protons + no. Neutrons
How do you find the no. Neutrons
No. Neutrons = mass number - no. Protons
How do you find the electrons in an atom
No. Protons = no. Electrons
What is an isotope
Atoms with the same atomic number but a different mass number
What is the bottom number on nuclide notation
Atomic number
What is the top number in nuclide notation

What is the calculation for relative atomic mass
Ram = (percent x mass) + percent x mass)
