Asmall solid piece of wax is in a dish as shown below. the dish is briefly placed under a hot lamp.
imagine you could track one particle of wax. as the wax is heated (but not heated enough to melt), how would a particle in the wax move?

answers are in the pic

option C The particle would vibrate faster but stay in the same location.

The solid state of the matter is featured by the position of the atoms in tight packages where they cannot move of position but they vibrate.

As the temperature increases, the substance and the atoms gain energy and the vibration increases (the atoms agitate). Only when the solid melts into liquid the atoms can change of position.  

the catch is that the top numbers are atomic masses the bottom numbers are the numbers of protons and electrons in an uncharged atom. they are the number of that atoms as you would find them on the periodic table. further, the numbers on the left are used to determine the missing numbers on the right

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
