Hey there!
26 protons + 32 neutrons = 58
26 protons means the element is iron, which is Fe.
Find the charge by finding the difference between protons and electrons.
26 - 24 = 2 (+)
We have 58, Fe, and 2+.
Your answer is 58Fe2+.
Hope this helps!
The number of atoms of phosphorus in copper (II) phosphate [Cu3 (PO4)2] is determined by multiplying first 9.20 by 2 since there are two phosphorus atoms in the compound and multiplying again with Avogadro's number. The answer is 1.108 x 10^25 atoms.
