Elements try to become stable by attaining inert gas configuration. In the ionic compound sodium chloride (NaCl), sodium and chlorine attain stability by losing and gaining an electron, respectively. Identify a correct option assuming the above situation.
Elements try to become stable by attaining inert gas configuration. In the ionic compound sodium chloride (NaCl), sodium and chlorine attain stability by losing and gaining an electron, respectively. Identify a correct option assuming the above situation.
The correct options are
A Sodium forms positive ion
C Chlorine forms negative ion
Atoms form positive ions when they lose electrons and upon gaining electrons, they form negative ions. For example, sodium atom having 11 electrons and 11 protons forms a unipositive ion when it loses one electron to chlorine because the net positive charge on the nucleus due to protons is more than the total charge due to electrons.
Sodium has 11 electrons and 11 protons in its atom. It forms unipositive ion by losing an electron.
Chlorine has 17 electrons and 17 protons in its atom. It forms uninegative ion by gaining an electron.
Calculation:
Charge due to electrons in sodium ion: -10 (10 electrons. Lost one electron to chlorine)
Charge due to protons: +11 (11 protons)
Net charge on sodium ion : (+11) + (-10) = +1
