What is the relative charge of a NEUTRON?
What is its relative mass?
Explain what is meant by the term "ISOTOPES".
True or false? Most of the mass of an ATOM is located in the NUCLEUS.
Why do ATOMS have no charge?
How many NEUTRONS does an ATOM of the ELEMENT on the left have?
Why is the RELATIVE ATOMIC MASS of CHLORINE not a whole number?
Freda is building a model of an ATOM. She wants to use her prize turnip as the NUCLEUS.
The turnip has a RADIUS of 20cm. What will the RADIUS of the whole ATOM be?
TIP: YOU CAN'T TRUST ATOMS - THEY MAKE UP EVERYTHING. BUT TRUST ME ON THIS, YOU NEED TO KNOW YOUR PROTONS FROM YOUR NEUTRONS IF YOU WANT TO UNDERSTAND ALL THIS CHEMISTRY STUFF. SORRY.
