Question

which one of the following is most likely to be an ionic compound?
a ncl₃
b co
c bacl₂
d sf₄
question 10
10 points
which of the elements listed below would most likely form a nonpolar covalent bond when bonded to bromine?
a rb
b br
c c
d o

Explanation:

1. For the first question, ionic compounds typically form between a metal and a non - metal. Barium (Ba) is a metal and chlorine (Cl) is a non - metal in \(BaCl_2\), while the other options are composed of non - metals only.
2. For the second question, a nonpolar covalent bond forms between two atoms with the same electronegativity. When bromine bonds with itself (Br - Br), it forms a nonpolar covalent bond as the electronegativity difference is zero.

Answer:

1. C. \(BaCl_2\)
2. B. Br
