periodic table basics\n1. which elements had complete outer shells? give the name and symbol for each.\nwhat do you notice about the location of these elements?\n2. which elements had only one valence electron? give the name and symbol for each.\nwhat do you notice about location of these elements?

Answer

Explanation:

Step1: Recall periodic - table trends

Elements with one valence electron are in Group 1 (alkali metals).

Step2: List elements

Lithium - Li, Sodium - Na, Potassium - K, Rubidium - Rb, Cesium - Cs, Francium - Fr.

Step3: Observe location

They are all in Group 1 of the periodic table.

Answer:

Lithium - Li, Sodium - Na, Potassium - K, Rubidium - Rb, Cesium - Cs, Francium - Fr; They are in Group 1 of the periodic table.
