Question

I need help, please :)

Answer 1

C. Atom Y

Step-by-step explanation:

when calculating charge, the "Number of Neutrons" doesn't matter because neutrons have no charge. (so you can ignore the neutrons section for this question)

also, protons have a positive charge, and electrons have a negative charge

to solve this problem, add the charges of the protons and neutrons together to see if the number ends up positive (because question is looking for positive charge)

for Atom W:
`3+(-3) = 0`, so no, this isn't the answer. 0 is neutral charge

for Atom X:
`53 + (-53) = 0`, this isn't the answer either. 0 is neutral charge

for Atom Z:
`1+(-1)=0`, nope, 0 is neutral charge

for Atom Y:
`55+(-54) = 1`, yay this is it, 1 is positive which indicates positive charge.

therefore, C. Atom Y is the answer
