Cards in this deck (7)
- 1What is the relative charge and mass of a proton?Mass; 1
Charge: +1 - 2What is the relative charge and mass of a neutron?Mass: 1
Charge: 0 - 3What is the relative charge and mass of an electron?Mass: 1/1840
Charge: -1 - 4What is the definition of atomic number?The number of protons in the nucleus.
- 5What is the definition of mass number?The total number of protons and neutrons in the atom.
- 6What are isotopes?These are atoms with the same number of protons but different number of neutrons.
- 7Why do isotopes have similar chemical properties?This is because the electronic configuration is still the same. the only difference is that their physical properties are going to be different because they have different masses.
