Just so you know oxygen that is 60 miles up gives off a yellow-green color, but oxygen at higher altitudes about 200 miles above us gives the all red auroras. Ionic Nitrogen produces the blue light and neutral Nitrogen gives off the red-purple and the rippled edges.
Q) What is different between an ionic bond and a covalent bond?
A) An ionic bond is formed between a metal and a non-metal. ... Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds.
No. Radiation is not in the magnetic “criteria” so it would not be correct.
Explanation:
Hey It is due to physical properties
The hydrogen bonds that hold water molecules together in water's liquid and solid form give the substance high boiling and freezing points and strong surface tension. Because water molecules are held so tightly together, it takes a large amount of heat for water to boil.
