Q1 stuff pt. 2
100
What is the purpose of radioactive decay?
For unstable isotopes to become stable by emitting a kind of particle.
100
How do you write a ionic compound in general? What do you write first?
Cation first then Anion
100
Draw the stick diagram for N2
It should be a triple bond with 2 electrons on the outside for each N
100
What is the difference between gas and plasma?
Plasma has charged ions inside of it, and can conduct electricity.
100
Identify the three subatomic particles.
Proton, Neutron, Electron
200
Write Germanium-70 in nuclear notation.
Write Sodium-24 in nuclear notation
7032Ge
2411Na
200
Why are cations and anions bonding with eachother in an ionic compound?
Cations and Anions have charges which makes them unstable. Opposite charges attract each other, therefore they cancel out to create a neutral charge.
200
If we have 3 domains, what is the bond angle?
120 degrees
200
What is the law of conservation?
Matter can never be created nor destroyed
200
In electron configuration, how many electrons can you have per orbital (which can also be represented by boxes)
2 electrons only!
300
What are the three isotopes that is used in nuclear fusion? (Order from least amount of energy to greatest energy)
Deuterium (or hydrogen-2), Helium-3, Helium-4
300
What is the name of LiNO3
Lithium Nitrate
300
Any halogens needs ______ additional electron(s) to complete its octet
Halogens only have 7 valence electrons. Therefore they only need 1 to make 8.
300
Describe what phases is used in sublimation.
Solid turning into a gas
300
What happens when we apply extreme heat on a metal cation?
It releases energy in the form of a photon. (colored fire lab)
400
Write out the equation of Iridium-191 if it were to go through beta decay.
19177Ir => 0-1e + 19178Pt
400
What is the formula of Sodium Carbonate?
Na2CO3
400
What type of diagram uses a single dot to represent an electron?
What kind of electrons are represented in this diagram?
Lewis dot diagram.
Valence electrons
400
Name three metalloids.
Si, Te, B, Sb, Ge, As, At, etc.
Silicon, Tellurium, Boron, Antimony, Germanium, Aresnic, Astatine.
400
What is the full electron configuration of Aluminum?
1s22s22p63s23p1
500
Describe what is happening to the unstable isotope when an isotope goes through gamma decay.
In gamma decay, the electrons are getting excited and release photon energy.
500
When do we write the roman numeral in the name of an ionic compound? What does the roman numeral represents?
We only write the roman numeral when the metal charge is variable. The roman numeral represents the charge of an ion in the compound.
500
What is the name, shape, and bond angle for Cl2
Name: Chlorine Gas | Shape: Linear | Bond Angle: 180 degrees
500
Which one has higher ionization energy? Hydrogen vs Cesium
Cesium has more ionization energy.
Ionization energy trend: increase from bottom to top, increases from left to right.
500
What is the shorthand and full electron configuration of Calcium?
Shorthand: [Ar]4s2
Fullhand: 1s22s22p63s23p64s2
