What is the charge of an ion with p=9 n=10 e=10 ?

Explanation:

The element fluorine has 9 protons and 9 electrons. In the image on the right it has gained an electron and now has 10. Since it has 10 negative particles, but only 9 positive ones, its net charge is –1. A negatively charged ion is called an anion.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
