What else can I help you with?
What happens to atoms and molecules when a chemical change occurs?
They get rearranged to form new products.
Why doesn't an atoms identity change during a chemical change?
The energy involved in chemical reactions is not so strong to affect the identity of atoms; only nuclear reactions can modify an atom.
When a physical change in a sample occurs which does not change?
Substance in the material Remain the same
A blank bond occurs when two atoms share electrons to form compounds called molecules?
occurs in gas molecules; also known as diatomic elements.
What type of reaction occurs when atom combine to form molecules or when molecules break down into atoms?
Chemical reactions occur when atoms combine to form molecules (synthesis reaction) or when molecules break down into atoms (decomposition reaction). These reactions involve the rearrangement of atoms to form new substances with different properties.
What happens to atoms and molecules when a chemical change occurs?
They get rearranged to form new products.
If halogen atoms replaced hydrogen atoms in the molecules would the geometry of the molecules change?
Ya yo
Do atoms change during a physical change?
Nope. All that happens in chemical reactions is that atoms are rearranged into new molecules or compounds. You can't destroy atoms in a chemical reaction so whatever you begin with is what you end up with.

The energy involved in chemical reactions is not so strong to affect the identity of atoms; only nuclear reactions can modify an atom.
When the substance undergoes a chemical change its identity deos not change?
That's correct. In a chemical change, new substances are formed through rearrangement of atoms, but the identities of the original atoms remain the same. This is because atoms are not created or destroyed during chemical reactions, they simply rearrange into new combinations.

When a chemical reaction occurs atoms are never?
When a chemical reaction occurs atoms get ionized. Atoms are never created nor destroyed in a chemical reaction.
Do molecules stay the same during physical change?
Yes, during a physical change, molecules remain the same. The arrangement and motion of molecules may change, but the actual atoms that make up the molecules do not change.
What makes a chemical reaction different from a physical change?
In a chemical reaction, atoms are rearranged, such that some atoms get out of some molecules and join other molecules.
What happens during physical changes?
The transformation of a liquid to a gas.
