1.50 Which of the following statements could be true according to the atomic masses on the periodic table? E
Statement
True or
False
Explanation
False
a. Si-28 is higher in abundance than Si-30.
b. Argon consists of a roughly 50:50 mix of
Ar-36 and Ar-40
c. Strontium is predominantly composed of
Sr-86.
d. Neon is composed of a near equal mix of
Ne-20 and Ne-21

here are some of the ways in which chemical and nuclear reactions differ.

explanation:

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.
