what type of particle is present in figure 2?

po-215 i got it right on the quiz

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

answer

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
