Unit 3 General Chemistry Standards
I.
I can explain the arrangement of the elements on the Periodic Table, including the relationships
among elements in a given column or row.
A. Given the name or symbol of an element I can state its Group and Period.
B. I can identify whether an element is a metal, nonmetal or metalloid.
II.
I can explain the relationship of an element’s position on the Periodic Table to its atomic number
and electron configuration.
A. I can determine the number of valence electrons of an element from its Group and Period.
B. I can determine the outer electron configuration of an element from its Group and Period.
III.
I can identify and compare trends on the Periodic Table, including reactivity. I can use the trends to
explain the properties of subgroups, including metals, nonmetals, alkali metals, alkaline earth
metals, halogens and noble gases.
A. Given two elements I can use their position on the Periodic Table to predict which is more reactive.
B. I can describe three chemical or physical properties of the Alkali metal (Group I A), Halogens (Group VII A)
and Noble (inert) gases (Group VIII A).
