1) Answer. c and d both statements are correct.

Explanation:

Statement A is incorrect because anions are the species which are negatively charged.F^{1-},O^{2-} and N^{3-}etcF

1–,O 2−andN 3−etc .

Statement B is incorrect because non metals generally forms anions for example:

,O^{2-},Cl^{1-}, P^{3-},O

2−

,Cl

1−

,P

3−

Statement C is correct because when we write an ion we will first write symbol of that element than charge and then positive(cations) or negative(anions) sign. for example Na^{1+},Mg^{2+} and Br^{1-} etcNa

1+,Mg 2+andBr 1−

etc .

Statement D is correct because when anion is formed, electrons are gained.These number of electron depends upon the valency of that element.

sorry number 1 lang po alam ko
