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.
Ionization is a chemical change, as it involves the process of gaining or losing electrons to form charged particles (ions). This differs from physical changes, which do not alter the chemical composition of a substance.
Reduction is primarily a chemical change, not a physical one. It involves the gain of electrons by a substance, often resulting in a change in its chemical composition. In contrast, physical changes, such as changes in state or appearance, do not alter the substance's chemical structure. Therefore, while reduction is a crucial process in chemistry, it falls under the category of chemical changes.
Oxidation typically involves a chemical change where a substance loses electrons. While you might observe physical changes associated with oxidation, such as a change in color or texture of the material, the process itself is primarily a chemical change.
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.
An atom acquires a charge by losing or gaining electrons.
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.
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
