How is the geologic column used in relative dating

Relative dating can also be done by comparing the relative ages of rock layers in different areas. A geologic column is an ordered arrangement of rock layers based on the relative ages of the rocks, with the oldest rocks at the bottom.

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.  

c. electrical charges of ionic bonds.
