Answer 2

Answer:

Plzz mark me as brainliest

Explanation:

• Radical is a relating to or affecting the fundamental nature of something; far-reaching or thorough.

• For example, H2SO4 has two hydrogen atoms, so the valency of sulfate is two. ... Aluminum makes ions with a positive charge, which is why the sulfate ion has a negative charge, and that makes the sulfate radical have a 2- valency.
