Explain how a bright-line spectrum is produced, in terms excited state, energy, and ground state

cuz the  light is a fraction of the world is   screens like: tablets,tv,phones,computers. so the  world is like nothing to anyone revolves around electronics so if you lost your electronic for 3 dayscould you do it (p.s the finge is pointing  at you)

Explanation:

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
