Periodic Trends in Group
II
Objective
In this experiment, the trend in one of the several periodic
properties for group II of the Periodic Table will be
determined.
Introduction
Elements in the same group of the Periodic Table have similar
chemical and physical properties that gradually change as one goes
from one element in the group to the next. By observing the trends
in properties, the elements can be arranged in the order in which
they appear in the Periodic...

Lewis Diagrams for Atoms of Representative Elements by Period What are "E", if each of the following atomic electron-dot diagrams corresponds to a sixth period, representative element? Representative elements are those that belong to the groups 1,2,and 13-18 (IA - VIIIA) of the Periodic Table. Also called Main Group elements, they are characterized by having their outermost or valence electrons in s and p subshells. Determine the element's identity in each case. Enter the chemical symbols for the elements, in...
