Atoms have a negative charge when they gain electrons during chemical changes. Atoms are a basic unit of matter, and everything is made of atoms.

Breaking of bonds but also formation of new bonds.
Yes. Photosynthesis involves the transfer of electrons. Photosynthesis causes a chemical change. All chemical changes involve either the transfer of electrons or a change in the configuration of electrons. No other way exists to make a chemical change.
A chemical change in which electrons are gained is a reduction.
Chemical change changes the electrons of matter, a physical change does not. Water is water as ice, water and steam, this is a change of state but physically there is no change of water it is a change of the energy content of water.
Physical changes do not make new substances and can be reversed. Chemical changes create new substances and are very difficult to reverse.
A physical change is a change in chemical composition. A physical change is a change where chemical composition is not altered. Not all chemical changes are accompanied by a physical change, but some are. The same is true for the reverse.

Physical changes can be undone. It is not possible to unfry a chicken. The heat casues chemical changes in the meat and in any coating.
non example of chemical change: one non example is ice. ice is NOT an example of chemical change.
Something that tarnishes goes through a chemical change versus a physical change.
Cooking food can cause chemical Changes
