Amplitude - CORRECT ANSWER: the maximum displacement of a particle at a peak or
trough
Atomic size - CORRECT ANSWER: - Distance between the outermost electrons and the nucleus
- Increases as you go down a group (gets bigger)
- Decreases as you go left to right in a period (gets smaller)
Electronegativity - CORRECT ANSWER: - A measure of the attraction an atom has for its outer shell electrons
- Decreases as you go down a group (looser, less attraction)
- Increases as you go left to right in a period (tighter, more attraction)
