Choose the correctly written and balanced chemical equation for the word equation below.
When aqueous beryllium chloride reacts with aqueous
silver nitrate, aqueous beryllium nitrate and solid silver
chloride form.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
