i think that in nuclear reactions but in normal reaction not created and destroyed
Added:
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.
Bonds are created when chemical reactions join atoms.
In an ordinary chemical reaction, mass is conserved; it is neither created nor destroyed. This principle is known as the law of conservation of mass, which states that the total mass of the reactants equals the total mass of the products. Thus, during a chemical reaction, atoms are rearranged, but their total quantity remains constant.
When a chemical reaction occurs atoms get ionized. Atoms are never created nor destroyed in a chemical reaction.
matter can not be created or distroyed
No. Atoms, which are matter, are neither created nor destroyed in a chemical reaction, but they are rearranged.
In any chemical reaction atoms are neither created nor destroyed.
Atoms are never created or destroyed in a chemical reaction. There are the same number of each type of atom both before and after a chemical reaction. Atoms are never created of destroyed; the molecules are just re-arranged in their bonding with each other.
During a chemical reaction, atoms are rearranged and bonded together in new ways, forming different substances. The total number of atoms remains the same before and after the reaction, as atoms are neither created nor destroyed in a chemical reaction.
How was energy created at the beginning of time? If energy cannot be created nor distroyed then how did it originate?
It is a covalent bond.
Individual atoms in a chemical reaction are rearranged to form new chemical compounds. Atoms are not created or destroyed in a chemical reaction, only the way they are arranged changes. The total mass and number of atoms of each element involved in the reaction remain constant, following the law of conservation of mass.
Chemical reactions involve the combination, separation, or rearrangement of atoms. During those processes atoms are not subdivided, created, or destroyed.
