... Oxygen takes the electron density from other atoms when it forms two bonds, to become a negative two ion. Do Negative ions help you sleep? The subjective results indicate that with negative oxygen ions subjects fell asleep easier, meanwhile, the objective results indicate that the duration...
When going down the group, the number of electrons around the nuclei increases, adding new orbitals to the atom and that increases the size of the... Learn more about this topic: Periodic Table Groups vs. Periods | Properties & History ...
How does the addition of ions affect the rate of fading of dye? Why are anions always larger than the atoms from which they are formed? Explain why 2-bromopropane react with sodium iodide in acetone over 10^4 times faster than bromocyclopropane. Hint: Examine the transition state for each...
Why do atoms form bonds? How to determine valence electrons? Why do ions form covalent bonds (polyatomic ions) if they already have complete valence shells due to their ionizing? Why do halogens have high electron affinity? Why do covalent bonds form?
Why don t atoms gain or lose protons?Atoms never gain protons; they become positively charge only by losing electrons. A positive ion is called a cation (pronounced: CAT-eye-on). You may have notice that the number of neutrons in each of these ions was not specified. ...
The aurora borealis and aurora australis have dazzled us in the night sky for centuries. Here’s what causes them—and why we’re seeing them more lately.
The structures of pure metals are simple to describe since the atoms that form these metals can be thought of as identical perfect spheres. More specifically the metallic structure consists of 'aligned positive ions' (cations) in a "sea" of delocalized electrons. This means that the electrons ...
Okay, I was going to say that some atoms don't do this, but I didn't. Some atoms are an exception to this rule. I'm sorry for assuming you were fighting. Now, if you'll give me another chance, could you explain to me why, only in these certain atoms, do they become stable,...
giving the resultant atom a net positive charge (when an electron is lost) or a net negative charge (when one is gained). These charged atoms are called ions, and oppositely charged ions can be attracted together to form an ionic bond and an electrically neutral molecule, such as NaCl, or...
Why do ions form covalent bonds (polyatomic ions) if they already have complete valence shells due to their ionizing? How do hydrogen atoms make a covalent bond? Why do ionic bonds have high melting points? Why is ammonia (NH3) a covalent bond?
