N=1 shell contains 2 electrons.
n=2 shell contains 5 electrons.
n=2 is the outermost shell. Therefore there were 5 electrons before sharing.
6 electrons are being shared between 2 nitrogen atoms.
Pair of electrons form a covalent bond. Therefore 3 pair of electrons will form 3 bonds.
Answer:
D
Explanation:
I hope this right, I'm sorry if it's not.
For an atom to be neutral, it has to have the same amount of protons and electrons. Because protons and electrons have opposite charges, when there is an equal amount of them they balance each other out
Explanation:
hope the picture above help u understand:)
Answer:
if you add a neutron to lithium-7 it becomes a compound nucleus of lithium-8
Weakly basic drugs behaves different from acidic drugs which is discussed below.
<h3><u>Explanation</u>:</h3>
Weakly basic drugs are those drugs which have an amine group associated with them. They are able to gain a proton to be come positively charged.
So drugs like quinine, ephedrine and aminopyrine which are basic got completely ionised in stomach.
The stomach can absorb those compounds which are lipid soluble. The acidic drugs like alcohols, Salicylic acid, aspirin, thiopental, secobarbital and antipyrine etc which are acidic gets absorbed by means of <em>diffusion</em> through the membrane.
But the basic drugs have charges on them which makes them lipophobic. So they cannot get absorbed through stomach. However weakly basic drugs sometimes get absorbed depending on their ionisation extent.
The rest goes to small intestine which has basic environment and there they gets absorbed via diffusion or facilitated diffusion.
