How does a lightning rod protect a
building from lightning damage?

Answer/Explanation:

A lightning rod is a metal rod that is used to dislocate where lighting hits. Lightning is going to hit the closest point that it has been attracted too. So, the lightning rod was invented to attract lighting to something less potentially dangerous. Instead of hitting a building causing fires and collapsing, it takes the bolt so that nothing else has to.

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
