As we move across the periodic table of elements, certain trends are evident. The placement of individual elements in the period
ic table allows us to predict many characteristics of elements such as state of matter at room temperature, reactivity, and valence electrons just to name a few. Let's compare the elements in Group #1 and Group #17. Identify the differences in the two families based on their locations in the periodic table. Choose ALL that apply Question 20 options:
Group #1 elements are metals and Group #17 elements are nonmetals.
Group #1 elements form negative ions while Group #17 form positive ions.
Group #1 elements are reactive while Group #17 elements are non-reactive.
When forming compounds, Group #1 elements lose electrons and Group #17 elements gain electrons.
