1. F


2. F


3. F


4. T


5. F





i think you messed up on Q 2These are science questions True OR False?
1. False, O=8 H=1


2. False, atomic number is the number of Protons


3. False ,


4. True


5. False, atomic number is the number of Protons but atomic mass is number of Protons and neutrons together.
1) FALSE


2)False (you need to find the no. of protons AND neutrons, sum them to find mass number)


3) False


4)True


5) False (atomic number = no. of protons.


Mass number = no. of protons +neutrons)
