Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What causes an atom to be charged?
A
gain or loss of electrons
B
gain or loss of protons
C
gain or loss of neutrons
D
None of the above
Explanation: 

Detailed explanation-1: -Ionization is the process by which ions are formed by gain or loss of an electron from an atom or molecule. If an atom or molecule gains an electron, it becomes negatively charged (an anion), and if it loses an electron, it becomes positively charged (a cation).

Detailed explanation-2: -Atoms and chemical species lose or gain electrons when they react in order to gain stability. Thus, typically, metals (with nearly empty outer shells) lose electrons to non-metals, thereby forming positive ions. The number of electrons depends on their position on the Periodic table (in simple terms).

Detailed explanation-3: -When an ionic compound forms, the more electronegative element will gain electrons and the less electronegative element will lose electrons.

Detailed explanation-4: -For an object to become charged, it must either gain or lose electrons. Losing electrons results in more positive charge than negative charge, making the object charged positively. Gaining electrons results in more negative charge than positive charge, making the object charged negatively.
