Final answer:
The more metallic element between As and Sn is Sn (tin).
Step-by-step explanation:
From the given options, the more metallic element between As and Sn is Sn (tin).
Tin (Sn) is a metallic element, while arsenic (As) is a metalloid. Metallic elements typically have properties such as high electrical and thermal conductivity, luster, and malleability. Metalloids, on the other hand, have properties that are intermediate between metals and nonmetals.
Tin is a silvery-white metal that is relatively soft and malleable. It has good electrical conductivity and is used in various applications, such as soldering, coating for food cans, and bronze alloys. Arsenic is a metalloid with a brittle, dark gray appearance. It has limited use in various industries, including the production of semiconductors and pesticides.
