Atoms when gain electron/s during the formation of ionic bond, they become negatively charged and are called…….
a) ions
b) cations
c) atoms
d) anions
The force of attraction between cations and anions in a compound is called……
a) bond
b) ionic bond
c) force
d) covalent bond
Ionic bond is
formed between metal and…….
a) metalloid
b) metal
c) non-metal
d) all of these
Sodium atom has 1 electron in its valence shell. Which of the following it forms?
a) cation
b) anion
c) both
d) none
Explanation:Cations are positively charged ions. They are formed when a metal loses its electrons. They lose one or more than one electron and do not lose any protons.
Chlorine atom has 7 electrons in its valence shell. Which of the following it forms?
a) cation
b) anion
c) both
d) none
Explanation:Anions are negatively charged ions. They are formed when non-metal gains the electrons. They gain one or more than one electron and do not lose any protons. Therefore, they possess a net negative charge. Some examples of anions are Iodide (I–), chloride (Cl–), hydroxide (OH–).
Sodium loses one valence electron and attain the electronic configuration like stable…….
a) helium
b) neon
c) argon
d) xenon
