Flashcards in Atoms Deck (9)
What are degenerate orbitals?
Orbitals of the same energy
The energy of the electrons is limited to specific values
Why is the shape of the electron important?
1. Occupy 3 dimensions
2. Calculated mathematically
3. Region you are most likely to find an electron
What is relative atomic mass (RAM)?
Based on the element's isotopes and the relative abundance of those isotopes ( how much of each occurs in nature)
What is an isotope?
Atoms of an element with the same number of protons but varying numbers of neutrons, and thus have varying masses.
What is the nucleus?
1. Where them ads of the atom is concentrated
2. Contains nucleons
3. Positively charged
4. Held together by a strong nuclear force
What are the main sub- atomic particles?
What is the value of a.m.u?
