How did the study of the atom contribute to our understanding of the periodic table of the elements? Experiments that identified characteristics of atoms provided scientists with atomic weights and atomic numbers, which were used to organize the periodic table. The determination of electron charge led to an understanding of how atoms interact with one another, which facilitated the organization of the periodic table. Atoms are representative of elements, so scientists scaled up atomic characteristics to understand elemental characteristics, allowing scientists to arrange elements in a periodic table. Elements are made of atoms, so understanding atoms provided information about elements, which led to the organization of the periodic table.

Mass spectrometric analysis showed that there are four isotopes of an unknown element having the following masses and abundances: Three elements in the periodic table that have atomic weights near these values are lanthanum (La), atomic number 57, atomic weight 138.9055; cerium (Ce), atomic number 58, atomic weight 140.115; and praseodymium (Pr), atomic number 59, atomic weight 140.9076. Using the data above, calculate the atomic weight, and identify the element if possible.

1. Hydrogen is a Group I element and each hydrogen will contribute I valence electron. Carbon is a Group (Roman numeral) element and each carbon will contribute ___ (number) electrons. Every oxygen atom in a compound will contribute valence electrons. Chloromethane has the molecular formula . Its skeleton is and the number of valence electrons may be determined as follows. There are three hydrogen atoms, each of which contributes 1 valence electron; the single carbon contributes 4 electrons; and the single chlorine atom contributes 7 electrons, making a total of 14 . A convenient tabular form of this calculation is
