How are atoms of a substance affected by a chemical change?
the atoms change in number
When ice changes to water the link up of atoms does or does not change?
The bonds between hydrogen and oxygen atoms of individual water molecules do not change when liquid water changes to ice. This is a physical change called freezing, and does not cause any chemical changes to occur. Only chemical changes can cause changes in chemical bonds.
How else are nuclear reactions unlike chemical reactions?
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
Does the number of atoms entering the reaction stay the same as the number put out by the reaction?
Chemical reactions do not change the number of atoms so yes, the number of atoms stays the same.
Explain chemical changes in terms of the structure and motion of atoms and molecules?
a chemical change destroys the old atoms and molecules to make completely new ones and a completely new substance.
Are the atoms in a substance the same if the substance changes states?
On heating there will be a change in the physical state not chemical composition. So the number of atoms will be the same even after change in state.

When atoms gain electrons during chemical changes what change do they acquire?
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.
What atoms gain electrons during chemical change what change do they acquire?
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.
What is it called when changes occur when bonds form between atoms?
A chemical reaction, a chemical change.
Does melting lose atoms?
No. Changes of state do not change the number of atoms.
Why do experiements change color?
because of the chemical changes taking place between the atoms involved...

When changing a subscript in a correctly written chemical formula it will change what?
Changing the subscript in a chemical formula changes the number of atoms to which the particular subscript belongs. Doing this changes the formula completely, making it representative of another substance completely.
