The number of neutrons in H2SO4 are:

Correct answer: C. 48

  • A. 50
  • B. 49
  • C. 48
  • D. 44

Explanation

No. of (proton=electron)=(atomic no.)No. of neutron=Atomic no. - no. of protonIn case of H2SO4,H2 = 2 protons & 2electronS = 16 protons, 16 electrons and 16 neutrons.O4 = 32 proton, 32electrons and 32 neutrons.Totals in H2SO4 ...Protons = 50, Electron = 50 and Neutrons = 48

About Electronic Configuration

Electronic configuration describes how electrons occupy shells, subshells and orbitals around an atom. Questions use the Aufbau principle, Pauli exclusion principle and Hund's rule to write configurations, identify valence electrons, form ions and explain periodic trends, including common exceptions such as chromium and copper.
