PLEASE READ! GUYSSS THIS IS WHAT THEY ARE DOING IN THE VACCINE!! SEARCH UP "ChAdOx1 researchsquare. com" AND I WANT YOU TO COPY AND SEARCH UP EVERY WORD THAT LOOKS SCIENTIFIC DONT IGNORE THOSE TYPES PLEASE THERE ARE LUNG TISSUES AND FEMALE & MALE FETUS THEY ARE GOING TO KILL US DO YOUR RESEARCH DONT TAKE THE VACCINE! ITS FOR YOUR OWN SAFETY! LIKE MRC-5 AND ALL THAT PLEASE!!!

Well, it seems legit because I took like 1 or 2 classes where we learned about RNA sequencing.

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.
