Fichas del conjunto (11)
- 1Atomic structureProton= mass 1 and charge 1+
Neutron= mass 1 and charge 0
Electron= 1/2000 and charge 1- - 2Atomic number Mass numberAtomic number- number of protons
Mass number- number of protons + neutrons - 3Location in atomProton-nucleus
Neutron-nucleus
Electron-shell - 4IsotopesTwo atoms of the same number of protons
but a different number of neutrons. - 5IonisationIf an atom becomes an ion, it loses or gains
an electron. If it loses an electron = 1+, if it gains an electron it becomes 1-. - 6Radioactive decayIf a substance is classed as radioactive it means that they are unstable and continuously gives out radiation at random intervals.
- 7BecquerelsAmount of radioactive decay per second
- 8Alpha radiationCharge=2+, Mass=4 amu, least penetration but most ionising. Helium Nucleus
- 9Beta radiationCharge=-1, Mass= 1/2000, middle penetration out of the three, 2nd most ionising out if the three. Fast electron.
- 10Gamma radiationCharge=0, Mass=0 amu, most penetration and least ionising. Electromagnetic radiation.
- 11Half lifeThe time taken for the radioactivity of specified isotope to fall to half life of its original value.
