Question

1. each column or group in the periodic table is called a family. elements are organized into fan according to their physical and chemical properties. identify the elements that belong to each fan based on the number of valence electrons. give the name and symbol for each element. hint: you will only use the elements you colored in step 8! alkali metals - 1 valence electron sodium na li lithium alkaline earth metals - 2 valence electrons ca calcium ba barium boron family - 3 valence electrons carbon family - 4 valence electrons nitrogen family - 5 valence electrons oxygen family - 6 valence electrons halides - 7 valence electrons noble gases - complete outermost shell

Explanation:

Elements are grouped in the periodic table based on valence - electron numbers. Each family has a characteristic number of valence electrons. For example, alkali metals have 1 valence electron, alkaline earth metals have 2, etc.

Answer:

Alkali Metals - 1 valence electron: Sodium (Na), Lithium (Li)
Alkaline Earth Metals - 2 valence electrons: Calcium (Ca), Barium (Ba)
Boron Family - 3 valence electrons: Boron (B), Aluminum (Al)
Carbon Family - 4 valence electrons: Carbon (C), Silicon (Si)
Nitrogen Family - 5 valence electrons: Nitrogen (N), Phosphorus (P)
Oxygen Family - 6 valence electrons: Oxygen (O), Sulfur (S)
Halides - 7 valence electrons: Fluorine (F), Chlorine (Cl)
Noble Gases - Complete outermost shell: Helium (He), Neon (Ne)
