Which substance in the data table above represents an ion with a +1 charge?
A.
Lithium
B.
Fluorine
C.
Potassium
D.
Sulfur
A. Lithium
To determine which substance in the data table represents an ion with a +1 charge, we need to look for an element that forms a cation by losing one electron.
Among the options given:
A. Lithium has an atomic number of 3, and it can lose one electron to form a cation with a +1 charge.
B. Fluorine has an atomic number of 9, and it tends to gain one electron to form an anion with a -1 charge.
C. Potassium has an atomic number of 19, and it can lose one electron to form a cation with a +1 charge.
D. Sulfur has an atomic number of 16, and it tends to gain two electrons to form an anion with a -2 charge.
Therefore, the substance in the data table that represents an ion with a +1 charge is C. Potassium.
To determine which substance in the data table represents an ion with a +1 charge, we need to look for elements that commonly form ions with a +1 charge. The data table is not included in the question, so we will have to analyze the properties of the elements mentioned.
A. Lithium: Lithium is a metal in group 1 of the periodic table. Group 1 elements, also known as alkali metals, tend to lose one electron to form a +1 ion. Therefore, lithium can form an ion with a +1 charge.
B. Fluorine: Fluorine is a nonmetal in group 17 of the periodic table. Nonmetals generally gain electrons to achieve a stable electron configuration and form negatively charged ions. Therefore, fluorine does not form ions with a +1 charge.
C. Potassium: Potassium is also a metal in group 1 of the periodic table. Similar to lithium, potassium tends to lose one electron to form a +1 ion. Therefore, potassium can form an ion with a +1 charge.
D. Sulfur: Sulfur is a nonmetal in group 16 of the periodic table. Nonmetals generally gain electrons to achieve a stable electron configuration and form negatively charged ions. Therefore, sulfur does not form ions with a +1 charge.
Based on this analysis, the substance that represents an ion with a +1 charge is either A. Lithium or C. Potassium.
