Atoms QuizBy LJ, Chels and
Gabrielle
Who invented the ‘plum pudding’ model?
RutherfordDaltonThomsonBohr
Which two subatomic particles have the same mass?
Protons and electronsNeutrons and electronsProtons and neutrons
What is definition of an isotope?
The number of electrons in an atomAtoms of the same element that have a dif
ferent amount of neutrons in the nucleusThe mass number of an atomThe atomic number of an atom
What is the charge of the nucleus?
PositiveNegativeNo charge (neutral)It depends on the atomic number and the
mass number
How are ions formed?
Gain or loss of electronsGain or loss of neutronsGain or loss of protonsSpontaneous combustion
What defines an element?
The atomic numberThe mass numberThe number of neutronsThe number of electronsThe number of protonsWhether or not it is an ion/isotope
How do you get an ion?
Electron – neutronNeutron – protonNeutron – electronProton – neutronProton – electronElectron – proton
What is the number of protons, neutrons, and electrons of 9
4Be2+
P=4, E=8, N=7P=4, E=2, N=5P=2, E=5, N=4P=5, E=4, N=2
What type of charge does a neutron have?
PositiveNeutral (none)Negative+2
Where can you find the protons and neutrons in an atom?
Outside the nucleusRevolving around then nucleusInside the nucleusIn Japan
Where can you find electrons?
Under my bedRevolving around the nucleusInside the nucleusIn select energy drinks
