A neutral atom of barium lost two electrons, how many electrons would be left?

false

because it does not have the potential to be entirely used up

the answer is   c.) 1575 j.

explanation:

the answer is c i believe

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
