Hydrogen is a
covalent bond. (A bond where one or more pairs of electrons are shared by two atoms)
In solid water gets cooled,in liquid the state of water is normal and in gas water gets vaporised.
Neon and helium both have full valence shells. This means that the out-most electron shell of the atom is full. In neon, the valence shell is 8 electrons, represented by the number of atoms in the family. In helium, the valence shell is only 2 electrons, which is what it has.
Hi!
First of all, the melting of ice cream is not a chemical reaction, because there is no change in the components of the ice cream and if you freeze the ice cream again, you will get the same ice cream that you had previously.
The melting of ice cream is an example of a physical change, in which a substance goes from solid to liquid state, and it is an endothermic physical change.
When you freeze ice cream, the heat is removed from the ice cream, making it an exothermic process, when heat is liberated to the environment and it's taken away from the substance, in this case, the ice cream.
