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.

chemical reactions are involved by the participation of electrons only.During chemical reaction number of protans remains as it is. No change in number of protans.Number of protans is also called atomic number.So no change in number of protans means no change in atomic number. That's why atomic number is not change during a chemical reaction.
Catalysts doesn't undergo a chemical change during a chemical reaction.
Tungsten generally loses electrons when forming bonds, it is a metal
A catalyst undergoes no chemical change during a chemical reaction.
The electron configuration of an atom determines the number of valence electrons, which are involved in chemical reactions. Atoms with few valence electrons tend to lose electrons to achieve a stable configuration, like group 1 elements (e.g., sodium). Conversely, atoms with nearly full valence shells tend to gain electrons to attain stability, as seen in group 7 elements (e.g., fluorine). This interaction between electron configuration and valence electron number dictates an atom's tendency to give up or gain electrons during a chemical change.
atoms, are rearranged during a chemical change.
when a chemical change occurs, chemical bonds are broken up
During a chemical change, matter is rearranged to produce new forms of matter. This is a result of either the sharing or transfer of electrons between different atoms. Observable evidence of a chemical change can be, but is not limited to, the formation of bubbles, a change in color or temperature, and the presence of a smell.
No. Nonmetals generally gain electrons during chemical reactions.
Non-metals during a chemical combinations tend to gain electrons. Metals in chemical reactions will tend to lose their electrons easily.
A catalyst does no change chemically.
