4.1.1.3 · Models of the Atom
What did scientists think atoms were before the electron was discovered?
Show the answerHide the answer
Tiny solid spheres that could not be divided.
4.1.1.7 · Electronic Structure
How are electrons arranged in an atom?
Show the answerHide the answer
In energy levels (shells), filling the lowest available (innermost) levels first. First shell holds 2, then 8, then 8 for the first 20 elements.
4.1.2.4 · Group 0 — Noble Gases
Why are the noble gases unreactive?
Show the answerHide the answer
Their atoms have stable arrangements of electrons: a full outer shell (8 electrons, or 2 for helium), so they don't need to lose, gain or share electrons.
