Question

Which elements can form acidic compounds? Check all that apply.

A. sulfur
B. rubidium
C.arsenic
D. selenium
E. silicon
F. xenon
H. antimony

Answer 1

The elements that can form acidic compounds from the list provided include Sulfur, Arsenic, Selenium, Silicon, Xenon, and Antimony. These are nonmetals or metalloids capable of forming covalent bonds with hydrogen and thus, creating acid when combined with water.

Step-by-step explanation:

The elements that can form acidic compounds are typically nonmetals or metalloids that have the ability to form covalent bonds with hydrogen. Thus, the elements from the student's list that can form acidic compounds include:

• Sulfur (A)
• Arsenic (C)
• Selenium (D)
• Silicon (E)
• Xenon (F)
• Antimony (H)

These elements are known to form oxides or other compounds that can react with water to produce acids, such as sulfur dioxide (SO2) which can form sulfurous acid, and silicon dioxide (SiO2) which can form silicic acid. Elements like rubidium (B), which is an alkali metal, typically form basic compounds when they react with water, hence rubidium would not form an acidic compound.
