How many molecules are in 45.0 grams CH4?
What is Ionization Energy?
Energy Required to Remove and Electron
Atomic radii of Al = 1.18 Å and Si = 1.11 Å.
Si has 4 unshielded protons (protons – core electrons), which attract the valence electrons closer to the nucleus than the 3 unshielded protons in Al.

How are the following three atoms related: C-11, C-12 and C-13
What is all three isotopes of carbon?
True or False
The orbitals are filled from highest energy level to the lowest energy level.
What is false?
237.98 amu
What is Coulombs Law?
Increase or Decrease
First ionization energies for B = 801 kJ/mol and Al = 578 kJ/mol.
The ionized electron for B comes from the second energy level, which is at a lower energy state than the ionized electron from Al, which comes from the third energy level ∴ it takes more energy to ionize.

What is [Kr] 5s2 4d9
How many neutrons does Gold-197 have?
What is 118 Neutrons?
True or False
Two electrons can occupy a single orbital if they have the same spin.
False
These two numbers are ALWAYS equal and never change.
What is atomic number and number of protons?
How many total atoms are in 5.8 mol CaCl2?
Calculate the empirical and molecular formulas of adrenaline. The compound has a molecular mass of 183 g/mol, and is 59.0% C, 7.1% H, 26.2% O, and 7.7% N by mass.
C9H13O3N
For Na, the first ionization energy I1 = 495 kJ/mol and second ionization energy I2 = 4562 kJ/mol
I2 is much larger than I1 because the second ionized electron comes from the core rather than valence shell.

What is [Xe] 6s2
The mass number of a lead isotope with 125 neutrons
What is 207?
True or False
Electrons in 1s would have a lower binding energy compared to electrons in 2s?
False
The part of the atom that contains the energy levels around the nucleus.
What is the electron cloud?
How many total ions are in 2.95 grams MgSO3?
Nicotine is 74.1% C, 8.6% H, and 17.3% N by mass. The molecular mass of nicotine is 162 g/mol. Calculate its empirical and molecular formulas.
C10H14N2
Why Nitrogen is smaller than Be.
N experiences an effective nuclear charge of +5 (Zeff=7-2=5), Be Zeff= +2. The valence e- of N are “feeling” the pull of 5 protons as opposed to 2 e- for Be
The electron affinities for Mg > 0 and Na = -53 kJ/mol.
The added electron to Mg must go into a higher energy state (3p) compared Na (3s) ∴ the loss in energy when an electron approaches a nucleus is offset by the electron's higher energy level.
