How many protons(p+), neutrons(n0) and electrons(e-) are in the atom 54Cr+3? Which of the following compounds has a chlorine atom with an oxidation state of +5? a) KClO3 b) V(ClO4)5 c) NaCl d) Cl2O3

Step 1
Chromium (Cr) has an atomic number of 24, which means it has 24 protons. The isotope notation 54Cr tells us that it has a mass number of 54, so we can find the number of neutrons by subtracting the number of protons from the mass number: 54 - 24 = 30 neutrons. Show more…
