Cards in this deck (7)
- 1What are ions?Ions have different numbers of protons and neutrons
- 2What is meant by the Mass Number?Tells you the total number of protons and neutrons in the nucleus
- 3What is meant by atomic number?Number of protons in the nucleus - identifies the element
- 4What are isotopes?Elements with the same number of protons but different number of neutrons (same elements)
- 5What are the relative charges of protons, neutrons and electrons?Protons = +1
Neutrons = 0
Electrons = -1 - 6What are the relative masses of protons, neutrons and electrons?Protons = 1
Neutrons = 1
Electrons = 1/2000 - 7Hydrogen, deuterium and tritium are all isotopes of each other. Identify one similarity and one difference between these isotopes.Similarity - They've all got the same number of protons/electrons
Difference - They all have different numbers of neutrons
