Answer 1

The given elements are matched with their atomic numbers: H-1, Na-11, Br-(-1, +1), Mg-2, Al-3, F-(-1, +1), O-8, Cl-(-1, +1), K-11, Ca-10, N-7, and C-4.

Step-by-step explanation:

To match the given elements/symbols with their atomic numbers and charges/ions, we need to identify each element's position in the periodic table and its common ion. Here's the correct match:

• H (Hydrogen) - B) 1
• Na (Sodium) - L) 11
• Br (Bromine) - A) -1, +1
• Mg (Magnesium) - C) 2
• Al (Aluminum) - D) 3
• F (Fluorine) - A) -1, +1
• O (Oxygen) - I) 8
• Cl (Chlorine) - A) -1, +1
• K (Potassium) - L) 11
• Ca (Calcium) - K) 10
• N (Nitrogen) - H) 7
• C (Carbon) - E) 4

Note: the charge/ions in the matches are the most common oxidation states for these elements. Not all elements listed commonly form ions with both a negative and positive charge, the matches simply connect each element to its respective atomic number and a potential ion state based on the periodic table.
