QuestionUse the group number to determine the charge on an ion derived from each element.
Part 1 of 4
Cesium: (Choose one) \square
Part 2 of 4
Strontium: (Choose one) \square
Part 3 of 4
Nitrogen: \square (Choose one)

Studdy Solution

STEP 1

1. Elements in the periodic table can form ions by losing or gaining electrons to achieve a stable electron configuration.
2. The group number in the periodic table often indicates the number of valence electrons an element has.
3. For main group elements: - Elements in groups 1 and 2 typically lose electrons to form cations with charges of +1 and +2, respectively. - Elements in groups 15, 16, and 17 typically gain electrons to form anions with charges of -3, -2, and -1, respectively.
4. Transition metals and other elements not in these groups may have variable charges, but this problem focuses on main group elements.

STEP 2

1. Determine the charge on the ion derived from Cesium.
2. Determine the charge on the ion derived from Strontium.
3. Determine the charge on the ion derived from Nitrogen.

STEP 3

Cesium (Cs) is in group 1 of the periodic table. Elements in group 1 have 1 valence electron and typically lose this electron to form a cation with a charge of +1.
Cesium ion charge: +1 \text{Cesium ion charge: } +1

STEP 4

Strontium (Sr) is in group 2 of the periodic table. Elements in group 2 have 2 valence electrons and typically lose these electrons to form a cation with a charge of +2.
Strontium ion charge: +2 \text{Strontium ion charge: } +2

STEP 5

Nitrogen (N) is in group 15 of the periodic table. Elements in group 15 have 5 valence electrons and typically gain 3 electrons to form an anion with a charge of -3.
Nitrogen ion charge: 3 \text{Nitrogen ion charge: } -3
Solution: Cesium: +1 Strontium: +2 Nitrogen: -3
