Answer : False

Explanation : Scientific models can never be changed this statement is False.

As these scientific models are based on current scientific knowledge and may have to be changed when new discoveries are made. They were not a replacement for experimentation, rather they were used in conjunction with experimentation to further understanding of a concept, event, or process. It has to be changed when the scientific understanding changes.

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
