Chlorine (Cl) shares common properties with which of the following elements?
A
Fluorine (F)
B
Sodium (Na)
C
Oxygen (O)
D
Neon (Ne)
Verified step by step guidance1
Identify the group or family in the periodic table to which chlorine (Cl) belongs. Chlorine is in Group 17, known as the halogens.
Recall that elements in the same group share similar chemical properties because they have the same number of valence electrons.
Look at the options and determine which element is also in Group 17. Fluorine (F) is in Group 17, while Sodium (Na) is in Group 1, Oxygen (O) is in Group 16, and Neon (Ne) is in Group 18.
Since Fluorine (F) shares the same group as Chlorine (Cl), it shares common chemical properties such as high reactivity and similar valence electron configuration.
Conclude that the element sharing common properties with chlorine is Fluorine (F) because they are both halogens in Group 17.
