The Brönsted-Lowry model focuses on the transfer of H⁺ in an acid-base reaction.

Explanation:

According to the theory of Brönsted-Lowry , an acid is a chemical substance capable of releasing hydrogen ions, while a base is that chemical substance capable of accepting hydrogen ions. That is, acids are substances capable of yielding protons (hydrogen H + ions) and substance bases capable of accepting them.

On the other hand, the conjugate base of a Brønsted-Lowry acid is the species that forms after an acid donated a proton. The conjugate acid of a Brønsted-Lowry base is the species that forms when a base accepts a proton.

Thus, the acid-base reaction is one in which the acid transfers a proton to a base (proton transfer H⁺).

This theory, unlike another theory like Arrhenius, does not require the presence of water as a means of reaction for the transfer of H⁺.

The Brönsted-Lowry model focuses on the transfer of H⁺ in an acid-base reaction.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
