Question

which of the following elements is most likely to have similar chemical properties to chlorine (cl)

• bromine (br)
• calcium (ca)
• sodium (na)
• argon (ar)

Explanation:

Step1: Recall periodic - table trends

Elements in the same group have similar chemical properties. Chlorine (Cl) is in group 17 (halogens).

Step2: Identify group of each element

Bromine (Br) is also in group 17. Calcium (Ca) is in group 2, Sodium (Na) is in group 1, and Argon (Ar) is in group 18. So bromine has similar chemical properties to chlorine.

Answer:

A. Bromine (Br)
