Hello There!
We will have water (H2O)
So if you drink a glass of water, you drink a glass of H2O.
Hope it helps! :)

Answer:
<u>One lone-Pair is present in Ammonia</u>
<u></u>
Explanation:
The number of valence electron in N = 5
The number of Valence electron in H = 1
The formula of ammonia = NH3
Total valence electron in ammonia molecule = 5 +3(1) = 5+3 = 8
The lewis structure suggest that :
Nitrogen completes its octet by sharing the electron pair with 3 hydrogen atoms. 
3 electron of Nitrogen are involved in sharing with Hydrogen 
So,<u><em> remaining two electron are left non-bonded</em></u> . Hence they exist as lone- pair
So, there is only 1 lone pair in the ammonia molecule .
The shape of NH3 is bent according to VSEPR theory . This is so because the presence of 1 lone pair causes more repulsion and occupy more space.
Thus the lone pair is changing the shape of the ammonia molecule . It also increase the dipole moment of the molecule , which gives polarity to it.

Answer: 27 neutrons 
Explanation:
Recall that the number of protons in the nucleus of an atom = Atomic number. 
Hence, Calcium with mass number 47 and atomic number 20 will have 20 protons 
Therefore, since Mass number = number of protons + neutrons 
47 = 20 + neutrons
Neutrons = 47 - 20 = 27
Thus, there are 27 neutrons in radioactive calcium nucleus.
