If atoms of same element combine, we say that element is existing in its real state (or simply a molecule of that element is formed). If two atoms of different elements combine, a compound is formed.
A new molecule is created.
A new compound is formed.
Chemical reactions involve the combination, separation, or rearrangement of atoms. During those processes atoms are not subdivided, created, or destroyed.
IT gains, looses, or shares outer electrons.
John Dalton
There are many types of atoms which combine quite easily with other atoms. Anytime you have a fire, something is combining with oxygen atoms. That is the easiest type of combination to bring about. But there are lots of other chemical reactions that can be easily made to happen. Put the right chemicals together and they will react.
There isn't one. The chemicals involved can contain millions of atoms, and it's not even just a single reaction; it's many thousands (at least) of reactions.
a molecule
Bonds are created when chemical reactions join atoms.
If atoms of same element combine, we say that element is existing in its real state (or simply a molecule of that element is formed). If two atoms of different elements combine, a compound is formed.
i think that in nuclear reactions but in normal reaction not created and destroyedAdded:No, never created or destroyed. Only in nuclear reactions some atoms may change in other atoms (by decay or fusion) but still not (totally) distroyed.
the change in the nuclei of the atoms.

atoms bcoz atom can neither b created nor destroyed.
John Dalton
During chemical reactions atoms remain unchanged.
Matter is neither created nor destroyed. Only change of bonds occur in atoms.
Chemical reactions occur when different atoms and molecules combine together and spit apart. For example, if Carbon (C) is burnt in Oxygen (O2) to form Carbon Dioxide, a Chemical Reaction occurs.So, during chemical reactions, new product atoms are not created, and old reactant atoms are not destroyed. Atoms are rearranged as bonds are broken and formed. In all chemical reactions, mass is always conserved...In chemical reactions, atoms rearrenge to form products...During chemical change atoms arrange and form new bonds. The new bonds are form to make the products.
