Gain, or loss, or sharing of electrons with other atoms.
It is no longer that same substance. A chemical changes the identity of the substance. Individual atoms cannot be broken down into smaller parts by normal physical or chemical change.
They get rearranged to form new products.
This happens when atoms are rearanged
the atoms change in number
The bonds between hydrogen and oxygen atoms of individual water molecules do not change when liquid water changes to ice. This is a physical change called freezing, and does not cause any chemical changes to occur. Only chemical changes can cause changes in chemical bonds.

the change in the nuclei of the atoms.
They break and new bonds are formed
An atom can gain, lose, or share.

Chemical
Because when something freezes, the atoms and molecules don't undergo a chemical change, they go through a physical change. By this, I mean that the individual atoms and molecules lose kinetic energy (energy that makes you move) in order to freeze. There is no chemical change here. Rather, the molecules and atoms are slowing down physically.
