The structure of an atom is very different from when atoms bond.
The structure of an atom, is basically the arrangement of the subatomic particles forming the atom. This includes the nucleus, made of protons and neutrons, and the electrons circling the nucleus.
When atoms bond together, it is when valence electrons are either taken from another atom or given to another atom to form a bond. Water, for example is a bond. It contains hydrogen and oxygen bonded together. This is where we get H2O. There are two atoms of hydrogen and one atom of oxygen to make the water molecule.

cell membrane
What structure brings about the change to alter the stimulus?

How can you alter you body type?
You can't; your body type is made up of factors you can't change, like your bone structure and metabolism.
Is air sensitivity a physical or chemical properties?
It is a chemical property as air sensitive compounds react with oxygen or air to yield a different compound. Physical properties don't alter the composition of the compound but rather the behaviour through different molecular arrangement.
What is a change in matter causing a substance to change into other substances with new chemical and physical properties?
That is officially known as a chemical change. It is distinct from a physical change which does not alter a substance into a different substance.
A functional group changes the structure of a compound but does not alter its chemical properties?
I'm pretty sure it's false... if you change a group the compound has to change because its not the same anymore
What does mean alter sentence structure?

How does doping alter the atomic structure of silicon?
It does not alter the atomic structure of the silicon at all, what it alters is the balance of bulk valence band and conduction band electrons in the crystal of silicon thus altering its bulk conductivity.
Chemical substances that alter perceptions and moods are?
Psychoactive (psychotropic) drugs alter perceptions and moods. One class of drugs which causes vast changes in perception is psychedelics.
What structure brings about the change to alter the stimulus?
The effector will act to counter the stimulus.
Can a physical change change what a substances is?
