Question

Arrange the following statements in a sequence which involves the calculation of the
atomic number and mass number for an atom of an element with 15 electrons and 16
neutrons.
I) A = Number of protons + Number of neutrons
A = Z + Number of neutrons
A = 15 + 16 = 31
II) Number of protons and number of electrons are equal in a neutral atom. Hence, the
atomic number Z is equal to 15.
III) Mass number is equal to the total number of protons and neutrons.
IV) Atomic number is 15 and mass number is 31.
A) II, IV, III, I
B) II, III, I, IV
C) III, II, I, IV D) III, II, IV, |​
