3)None of these

​

Answer 1

Answer:

1. Na⁺, Cu²⁺, Cl⁻

Explanation:

okkkkkkkl

Answer 2

Answer:

SO₄²⁻, NO₃⁻, NH₄⁺  simple radicals. (b)

Explanation:

Radicals are group of atoms of different elements that act as a single unit and have a net charge on them. Na⁺, Cu²⁺, Cl⁻ are ions because they have gained/lost electrons to become stable. Ions Ions are mostly formed in elements and radicals are mostly a group of atoms of different elements. Hence, over here, the radicals will be SO₄²⁻, NO₃⁻, NH₄⁺ because they are a group of atoms of different elements that act as a single unit and have a net charge on them.
