What is the difference between a mass number and a relative atomic mass?
Use the key words for a bonus point
Mass number is the sum of protons and neutrons for a single atom.
Relative Atomic Mass is the weighted average of the mass number of all natural isotopes of the element

Fill in the blanks:
NH4__ is a ___ion
NH4+ is a cation
300
True / false?
Valence electrons require the most energy to be removed during a chemical reaction
Bonus point: Tell me why?
False. Valence shell electrons are easiest to remove!
They are furthest away from the positively charged nucleus, so it has less attraction to the nucleus and can be easily removed.

Sam says "Nitrogen has a mass number of 14 and has 8 neutrons, so there must be 6 protons."
Explain whether Sam's statement is correct/ incorrect.
Sam's statement is incorrect. The number of protons is the same as the atomic number, so Nitrogen must have 7 protons.
There must be 14-7 = 7 neutrons
