Guess and check, test, trial and error, completion.
A strong chemical bond is formed by sharing electrons.
It would take 8 antacid tablets to produce 120 mL of CO2 gas.
Answer :
The steps involved in the electron dot structure of
are :
First we have to determine the total number of valence electron in
.
Number of valence electrons in N = 5
The charge on N is (-3). So, we add 3 electrons.
Total number of valence electrons = 5 + 3 = 8 electrons
