quantum theory and H atom
What quantum number defines the size of an orbital?
n
What type of bond forms between a metal and a non-metal?
ionic
How does the atomic radius change across a period?
Decreases
What type of bond is formed between Na and I?
ionic
What is the relationship between wavelength and temperature in blackbody radiation?
Shorter wavelengths are associated with higher temperatures. ie they are inversely proportional
what is the Pauli's Exclusion Principle?
Pauli's Exclusion Principle states that no two electrons in the same atom can have identical values for all four of their quantum numbers.
Is fluorine paramagnetic or diamagnetic?
It is paramagnetic as it has unpaired electrons
What are the characteristics of an ionic compound?
What does |Ψ|² represent in the Schrödinger equation?
Probability of finding an electron at a particular point
What is the electronic configuration of Cu?
[Ar] 4s1 3d10
Which group atoms absorb energy when they aquire an electron?
Atoms in group 2, group 18 and N
What is the electron pair geometry around an atom with 4 electron pairs?
Tetrahedral
How many radial nodes does the 2p orbital have?
radial nodes = n-l-1
for 2p orbital, n=2 and l=1
radial nodes = 2-1-1 = 0
what is the ground state electronic configuration of Br+2
[Ar] 4s2 3d10 4p3
why does ionization energy decrease from N to O?
the nitrogen atom has a half-filled atomic orbital and hence, it will be more stable than the oxygen atom. So more energy is required to remove an electron from N than O.
what is the formal charge on Cl in ClO3-
+2
