Which of the following statements is true about ions

Which of the following statements is true about ions?

A. Anions are positively charged ions.
B. Cations are common among nonmetals.
C. Charges for ions are always written as numbers followed by a plus or minus sign.
D. When an anion forms, more electrons are transferred to it.

An ion is formed only when an atom gains an electron or loses an electron.
There are two types of ions: cations or positively charged ions, and anions or negatively charged ions.
Formation if ions are caused by negatively charged particles known as only one electron.

All of the following are true except ion:

(a)- ions can be formed by adding an electron to a neutral atom
(b)- ions can be formed by removing an electron from a neutral atom
(c)- Ions can be formed by removing neutrons from neutral atom
(d)- ions can have positive and negative charges

Answer: Statements c and d both are correct.

Explanation:

Statement A is wrong because ion is the species which has negative charge.

B is false because nonmetals generally form ions.

Statement C is correct because when we write an ion, we will first write the sign of that element with charge and then the positive (cation) or negative (ion) sign.

Statement D is correct because when an ion is formed, electrons are gained. This number of electrons depends on the valency of that element.

Which Of The Segments Below Is A Secant

c. Charges for ions are written as numbers followed by a plus or minus sign.
