4d¹⁰ 5s² 5p⁶ is the electron configuration
I think it's D. helps to analyze the experiment because the purpose is to show how you got the conclusion that you did and how to keep track of any mistakes you might have made along the way.
Answer:
surface tension
Explanation:
Raindrops start to form in a roughly spherical structure due to the surface tension of water. This surface tension is the "skin" of a body of water that makes the molecules stick together.
Explanation:
Non-metals are the species which tend to gain electrons from a donor atom in order to attain stability.
Therefore, when a non-metal reacts with another non-metal then there will always be formation of a covalent bond. As covalent bonds are formed due to sharing of electrons.
For example,
is formed by sharing of electrons.
On the other hand, when a non-metal reacts with a metal then there will be formation of an ionic bond.
For example, LiCl is formed by transfer of electron from Li to Cl atom.
Thus, we can conclude that atoms of most non-metals share electrons and become bonded together into a molecule.
