What is A MODEL OF THE ATOMS?
What is THE ATOMS?
What ALWAYS stays the same in a chemical reaction?
What is THE NUMBER OF ATOMS?
What is the TYPE OF ATOMS?
Two substances look like clear liquid but a model shows they are made of different atoms. Will their other properties be the same or different?
What is THEY WILL BE DIFFERENT?
What is a substance?
What is SOMETHING MADE OF ALL THE SAME ATOMS?
What is SOMETHING MADE OF ALL THE SAME GROUPS OF ATOMS?
Do atoms change into different types of atoms during a reaction?
What is NO; THE ATOMS STAY THE SAME?
In a sealed container, two reactants form two products. Did any atoms escape?
What is NO; THE ATOMS STAYED IN THE CONTAINER?
TRUE or FALSE
During a chemical reaction, all of the reactants rearrange to form the products.What is TRUE?
Explain why substances have different properties.
What is THEY ARE MADE OF DIFFERENT GROUPS OF ATOMS?
Why do scientists use models to study atoms?
What is ATOMS ARE TOO SMALL TO SEE WITH THE HUMAN EYE?
Explain what “rearranging atoms” means.
What is THE ATOMS ARE THE SAME BUT SWITCH POSITIONS?
A reaction starts with two substances and goes through a chemical reaction.
What must have happened at the atomic level and what would you see after the reaction?
What is THE ATOMS REARRANGED?
What is YOU WOULD SEE NEW SUBSTANCES?
If a reaction starts with 10 atoms, how many atoms will there be after the reaction? Explain why.
What is 10 ATOMS; ATOMS CAN'T BE DESTROYED OR CREATED?
