What is the difference between arrhenius and brønsted-lowry acids and bases?

-arrhenius acids are not required to be in aqueous solutions because arrhenius acids can dissociate in any medium, not just water. therefore, arrhenius acids can be gases.

-all arrhenius acids are also brønsted-lowry acids because while dissociating, arrhenius acids always donate a proton and arrhenius bases always accept a proton.

-hydroxide ions are not bases according to the brønsted-lowry because hydroxide ions cannot accept protons and brønsted-lowry defines bases as proton acceptors.

Yes she is correct. the answer is completely correct

Answer : option a) 84explanation :

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
