Odd One Out
proton, electron, nucleus, positive
electron because a proton is positive and located in the nucleus
What charge does Fluorine have?
-1
What are the three subatomic particles?
Protons, Electrons, Neutrons
What are isotopes?
Atoms of the same element with the same number of protons but a different mass number (different number of neutrons)
What is the abbreviated electron configuration for sodium?
[Ne] 3s1
hydrogen, carbon, helium, oxygen
helium because it has all 8 electrons fulfilled (making it a noble gas)
What is the charge of NH4?
Where are electrons located?
Outside the nucleus because they have a negative charge (orbital)
How many neutrons does Carbon-13 have?
7 neutrons because 6 protons+7 neutrons=13
What is the abbreviated electron configuration for Barium?
[Xe] 6s2
protium, deuterium, tritium, ammonium
ammonium because the rest are isotopes of hydrogen
What is the charge of acetate?
-1
Where are protons/neutrons located?
Inside the nucleus
How many neutrons does Oxygen-18 have?
10 neutrons because 8 protons+ 10 neutrons = 18 atomic mass.
What is the abbreviated electron configuration for Calcium?
[Ar] 4s2
carbon-12, carbon-13, carbon-14
carbon-14 because it is unstable and has a half life of 5568 years
What is the charge of carbonate? What is the charge of calcium?
-2, +2
Which subatomic particle has the greatest mass?
neutron
How many neutrons does potassium-40 have
21 neutrons because 19 protons + 21 neutrons = 40 atomic mass
What is the abbreviated electron configuration of Lithium?
[He] 2s1
Carbon-13, Oxygen-18, Nitrogen-15, Lithium-7
Lithium-7 because the rest of them are isotopes
What is the charge of sulfate? What is the charge of phosphate?
-2, -3
What exactly are subatomic particles?
Particles smaller than an atom that are the building blocks which create an atom.
How many protons and neutrons, does hydrogen-4n have?
1 proton and 3 neutrons
What is the abbreviated electron configuration of oxygen?
