The image shows a portion of the periodic table. Which two elements have similar characteristics?
Element Periodic table of numbers for 8, 9, 10, 16, 17, and 18 are Oxygen orange color (15.9994), Fluorine red color (18.9984032), Neon Grey color (20.1797), Sulfur orange (32.065), Chlorine red (35.453) and Argon Grey (39.948).
A.
neon and fluorine
B.
chlorine and sulfur
C.
fluorine and chlorine
D.
oxygen and chlorine
E.
argon and fluorine
The two elements from the periodic table that have similar characteristics are: fluorine and chlorine and the correct option is option C.
Fluorine and chlorine are both halogens and belong to the same group (Group 17) in the periodic table. They share similar chemical properties, such as being highly reactive and readily forming compounds with other elements.
Both elements have a strong tendency to gain one electron to achieve a stable electron configuration, making them strong oxidizing agents. Additionally, they are both diatomic molecules in their natural state (F₂ and Cl₂), and they have similar electronegativities, which means they have a strong ability to attract electrons in a chemical bond.
Thus, the ideal selection is option C.

Ricardo and Maria conducted an experiment to test if the mass of a ball affects how fast it would roll down a ramp. They set up the experiment using a ramp and three balls of different masses. They tested each ball once and recorded their results. They concluded that the more mass a ball has, the faster it will roll down the ramp. Why is this experiment not reliable?
Their experiment was not controlled.
Their experiment did not test enough variables.
Their experiment was not performed multiple times.
Their experiment was not performed by multiple people.
