Multiple Choice
Which statement is not true about the electrical charges of elements on the periodic table?
A
Noble gases generally have a charge of zero.
B
Alkali metals typically have a +1 charge.
C
Transition metals always have a fixed charge.
D
Elements in the same group typically have similar charges.
Verified step by step guidance
1
Begin by understanding the concept of electrical charges of elements. Elements can gain or lose electrons to form ions, which have positive or negative charges.
Review the properties of noble gases. Noble gases are located in Group 18 of the periodic table and are known for their lack of reactivity due to having a full valence shell. This results in a charge of zero.
Examine alkali metals, which are found in Group 1. These elements typically lose one electron to form ions with a +1 charge.
Consider transition metals, which are located in the center of the periodic table (Groups 3-12). Unlike alkali metals, transition metals can have multiple oxidation states, meaning they do not always have a fixed charge.
Understand that elements in the same group often have similar charges due to having the same number of valence electrons, which influences their chemical behavior and the type of ions they form.
