As your question is vague, I am assuming that you are talking Alpha, Beta and Gamma radiation. Out of these three radiation, Gamma radiation is the smallest in size compared to Alpha or Beta, but it has the highest energy levels. Gamma radiation is also known as photons. In other words, photons are light particles.
The correct answer would be the last one.
There are six electrons in the covalent bonds.
Two N atoms would be :N:· + ·:N:
An N₂ molecule would be :N:::N: or :N≡N:
This gives each N atom an octet of eight electrons in its valence shell.
When water evaporates (which involves breaking of hydrogen bonds), it removes energy from its surroundings in a fashion that renders water an Excellent coolant.
Within water molecules, polar covalent connections are created between the hydrogen and oxygen atoms. The shared electrons are attached to the oxygen atom for a longer period of time than they are to the hydrogen atoms. A water molecule has no overall charge, but each hydrogen atom has a little positive charge, and each oxygen atom has a slight negative charge. The slightly positive hydrogen atoms repel one another and form the distinctive shape as a result of these charges. The positive and negative charges in the various regions of each water molecule cause them to attract other water molecules. Additionally, water forms hydrogen bonds with other polar molecules (like sugars) by attraction.
