How do the atoms of a molecule stay together?
a. chemical bonds
b. magnetic force
c. attraction of electrons and neutrons
d. through physical changes

The correct answer here is A. Chemical bonds are formed which are either covalent or ionic. In an ionic bond electrons transfer between atoms, whereas in covalent bonding atoms share their outermost electrons and gain stability as a molecule of the compound they are part of.

This is what i found on google“ the monomers combine with each other via covalent bonds to form larger molecules known as polymers. in doing so, monomers release water molecules as byproducts. this type of reaction is known as dehydration synthesis, which means “to put together while losing water. in the process, a water molecule is formed.” i hope this you
